Three fairies of light

1. Sunny Milk is a fairy who is the leader of the Three Fairies of Light composing of Sunny, Luna Child and Star Sapphire. She often pranks humans along with her two partners, using her ability to reflect light and thus make her or those around her invisible. Name: Sunny Milk Age: unknown, immortal Species: fairy Occupation: leader of the three fairies of light. She oftenly do pranks to human (even to Hakurei Reimu) along with her two partners Luna Child and Star Sapphire Height: 135 cm Weight: 30 kg Appearance: short early teen girl (based on appearance) with short ginger blonde/yellow hair braided at the sides of her head with red ribbons, blue eyes, as well as a pair of wings. She wears a red and white dress with long sleeves and frills, along with a pink ribbon attached at the top of the dress. She also wears red shoes, as well as a maid headband between her braids. Abilities: refraction of light. While she is reported to be considerably weak, her power allows her to change the refraction of light, making her able to hide herself or change how an environment looks. It is the same as being able to hide herself and make herself invisible. It is a fairy-like ability, mainly used in mischief, but her power gets weaker when the sun is not present, and rain gives away her illusions. The usage method of this ability has been confirmed to be as followed; by refracting light, she was able to make herself and others unable to be seen, give off light, bend the light of the sun & shine on shadows, and reflect danmaku that was made of light – she wasn't able to bounce back danmaku other than light. She can also accumulate sunlight inside herself, and release it in another moment. The power of the released light can be strong enough to blind people, generate considerable heat, and even start fires.As a lot of danmaku consists in light bullets, Sunny's ability is very useful in combat. She has already been seen surprising Yukari Yakumo and Okina Matara by deflecting their bullets. Also, by bathing in sunlight she is able to quickly recover her wounds, since she received the influence of sunlight the condition of the sun gives forth the quality of her ability.

Personality: Sunny is described as energetic and very curious. She also enjoys eavesdropping on others for things that might interest her, like clues for a treasure hunt. She is also fond of delicious foods and any kind of liquor. True to her namesake, she is much happier during clear weather whereby the sun is out. She occupies the highest level of house accordingly to receive the morning sunshine. Sunny often oversleeps late into the morning. In depth: Sunny Milk is an optimistic, mischievous fairy whose personality is defined by curiosity, playfulness, and a desire for fun rather than malice or ambition. As a fairy, she views life largely as a game, approaching situations with a childlike focus on the present moment and often acting on impulse without considering long-term consequences. She loves pranks, tricks, and turning ordinary events into adventures, usually motivated by amusement rather than a wish to harm others. Although often underestimated, Sunny is clever enough to devise schemes and exploit situations, but she lacks the maturity and foresight needed to predict the outcomes of her actions, making her more crafty than wise. She is naturally cheerful and resilient, rarely dwelling on failures or setbacks, instead quickly moving on to the next source of entertainment. Socially, she is outgoing and enjoys companionship, particularly with Luna Child and Star Sapphire, with whom she forms the Three Fairies of Light, often acting as the instigator who pushes the group toward new adventures. Sunny values freedom, friendship, excitement, and exploration over responsibility, status, power, or recognition, reflecting the carefree mindset typical of fairies in Touhou. Emotionally, she is affectionate, energetic, adaptable, and quick to recover from embarrassment, but beneath her confidence lies a vulnerability that emerges when situations become genuinely dangerous rather than playful. Her ability to manipulate sunlight and invisibility mirrors her character: bright, lively, elusive, and constantly creating both wonder and confusion. Overall, Sunny embodies a balance of confidence and fearfulness, cleverness and immaturity, independence and reliance on friends, making her a kind-hearted yet troublesome fairy whose greatest motivation is simply enjoying life and sharing that enjoyment with others.

2. Luna Child is a fairy and one of the members of the Three Fairies of Light, composed of her, Sunny Milk, and Star Sapphire. She often pranks humans along with her two partners, using her ability to negate sound and sneak around others. Name: Luna Child Age: unknown, immortal Species: fairy Occupation: member of three fairies of light. She oftenly do pranks to humans (even to Hakurei Reimu) along with her two partners Sunny Milk and Star Sapphire. Height: 135 cm Weight: 34 kg Appearance: Luna is a short early teen (based on appearance) girl. She has red eyes and short to the shoulder yellow hair, arranged into six princess curls on both sides of her head, as well as a pair of wings. She wears a white and black dress having long sleeves and a few black ribbons at the front of her dress, along with a big one below her neck and an even bigger one in her back. She also has a white shoulder cloth having black outlines, and a white beret with black ribbons attached on its sides. She wears a pair of slippers as well. When reading books, she's sometimes depicted with reading glasses. Abilities: muting (the surrounding) sounds. Luna is able to mute all the sounds around her. It is self-styled as "the ultimate fairy weapon in hide-and-seek". In hide-and-seek, it might seem that her ability is weaker than Sunny Milk or Star Sapphire – but, just like Sunny who manipulates vision, it is an ability suited for mischief, and it is not simply a specified range, and as she is able to consciously mute only a specified sound, it is very useful. However, since she also uses this ability even when it isn't necessary to mute sound, there are also instances of appealing for existence. Luna, much like her partners, is not very powerful. Her power when used in tandem with Sunny's power to refract light, they can be a powerful stealthy pair. Luna, much like Sunny Milk, gets weaker when her natural element, the moon, isn't present in the sky. Also, by bathing in moonlight, she is able to quickly recover her wounds. Since she receives the influence of moonlight, the condition of the moon gives forth the quality of her ability. Previously upon meeting Yukari Yakumo, she received advice regarding the true nature of the power of the "light of the moon", but due to tension, she did not hear anything but half of the talk, and for some reason she forgot (or was made to forget) the contents of the talk. Because of that, she probably wants to meet again the youkai she met at that time – Yukari; in actuality, she met her several times afterwards. Yukari said "the power of the light of the moon is even superior to the light of the sun. A peaceful power, the colour of the heart, sorrows, the light of the moon is a light that does not bewilder anything. Come now, wake up. Why do you think you are treated well by the other light of the sun and the light of the stars?" Personality: Luna is often described as clumsy and maybe even stupid at times, and is as curious as other fairies. She has a rare characteristic for a fairy: she loves coffee beans and is sometimes seen stealing some from humans, and she is also fond of alcohol. she's always tripping over something – even over nothing. Fairies are generally considered to have a quite different mindset compared to humans due to their unique nature. However, Luna's apparently depicted a bit different to the usual fairies: She tends to read books and newspapers, and has a habit of skeptical and rather logical thinking. Her common sense is more closer to humans in this regard. As result, the "stupid" she's commonly associated with is a lack of practical smarts, not book knowledge. In depth: Luna Child is the most cautious, sensitive, and emotionally aware member of the Three Fairies of Light, possessing a personality that balances curiosity and mischief with a greater degree of restraint and thoughtfulness than her companions. While she participates in pranks and adventures alongside Sunny Milk and Star Sapphire, Luna is generally less driven by excitement for its own sake and more concerned with the potential consequences, often serving as the voice of caution within the group. She tends to be timid, easily startled, and more aware of danger than the other two fairies, causing her to hesitate in situations where Sunny would rush forward without thinking. Despite this nervousness, she is not cowardly; rather, she possesses a realistic understanding of her limitations and prefers avoiding unnecessary risks. Luna is observant and emotionally perceptive, paying closer attention to moods, atmospheres, and social dynamics than many fairies, which makes her more empathetic and considerate of how actions affect others. Her sensitivity can also make her self-conscious and prone to worry, especially when facing uncertainty or conflict, but it contributes to her ability to understand situations from multiple perspectives. Unlike ambitious or power-seeking characters, Luna is motivated primarily by companionship, security, comfort, and the simple pleasures of everyday life, reflecting the fundamentally carefree nature of fairies while still displaying a deeper appreciation for stability and harmony. She values her friendships greatly and often relies on the support of Sunny and Star, finding confidence through their presence even when she feels anxious. Her ability to manipulate sound and create silence symbolically mirrors her personality: quiet, subtle, and often overlooked, yet capable of influencing her surroundings in significant ways without drawing attention to herself. Emotionally, Luna is gentle, kind-hearted, and relatively mature for a fairy, showing more patience and self-restraint than Sunny while lacking Star's confidence and analytical sharpness. She frequently acts as a moderating influence within the trio, helping prevent their schemes from becoming excessively reckless, though she still shares their love of fun, curiosity, and harmless troublemaking. Her greatest strengths are her empathy, caution, adaptability, and emotional awareness, while her weaknesses include insecurity, anxiety, indecisiveness, and a tendency to underestimate herself. Overall, Luna Child represents the quieter and more introspective side of fairy nature: a sensitive and thoughtful individual who seeks connection, safety, and happiness with her friends, preferring peaceful enjoyment and mutual companionship over excitement, conflict, or grand ambitions.

3. Star Sapphire is a fairy and one of the members of the Three Fairies of Light, along with Sunny Milk and Luna Child. She often pranks humans along with her two partners, using her ability to sense animate objects from a distance to her advantage. Name: Star Sapphire Age: unknown, immortal Species: fairy Occupation: member of the three fairies of light. Oftenly do pranks to human (even Hakurei Reimu) along with her two partners Sunny Milk and Luna Child. Height: 135 Weight: 32 kg Appearance: Star is short early teen (based on appearance) girl. she have long dark brown hair, a blue ribbon attached to it, and gray eyes, as well as butterfly-shaped wings. She wears a white and blue dress, the top part being mostly white, having a blue shoulder cloth, and the bottom part being blue. She has long sleeves and a blue piece of cloth attached around her waist, attaching as a ribbon in her back. She also wears boots. Abilities: detection of moving things. Like a radar, she is able to sense things that exist from afar. In Perfect Memento in Strict Sense, it became "moving things", but according to her speech and conduct as well as Shanghai Alice Correspondence Three Fairies Version, she is "only able to know moving things, and unrelated to being among that, living things" (for living things, she isn't able to make distinctions other than size). That said, she was able to detect Eternity when she was hibernating. Star, much like her partners, isn't very powerful. Her power allows her to know when trouble is coming or when to act during a prank. Unlike her two partners, her power does not weaken at any time, as stars are always present in the sky, even during the day. There hasn't been a depiction of concretely what range she is able to grasp things, but if she isn't preoccupied with other things, it seems that she's able to grasp a reasonably wide range, but it also seems that if there are a very large number of living things, then the important information gets buried. Also, she wasn't able to recognise Reisen Udongein Inaba who was invoking her own ability.There's hardly any instance where this ability caused direct damage in mischief, but as it's support orientated, in Perfect Memento in Strict Sense, it was even written that "when she is on observation duty, she can be a threat." If Star were not to slack off, then the three fairies' pranks would become quite nasty. As for recovery from injury – different from Sunny Milk and Luna Child's case – she isn't affected at all by the weather and constantly recovers at ease. As for how she slacks off, different from the other youkai and shinigami who are beaten, she uses her ability and skillfully slacks off. Personality: Star is often described as having more common sense than other fairies, being calmer, a bit wiser, often avoiding fights, letting her two partners do all the hard work for her, and making her getaway while her friends are busted in their pranks. As with her two other partners, she is rather fond of alcohol. Unlike her partners, she has the most bizarre sense of perception. Sometimes, when they see things that would cause Sunny and Luna to panic, such as an imminent incident or a mountain of human skulls, Star seems to find it fun and exciting.

Just as bizarre are also her interests, which include examining strange rocks, or keeping a mushroom bonsai tree as a hobby. Keeping to her namesake, she loves all things star related such as the Star Spangled Banner and Tanabata. In depth: Star Sapphire is generally the most perceptive, analytical, and strategically minded member of the Three Fairies of Light, combining the carefree nature of a fairy with an unusually sharp awareness of her surroundings. While she shares the same love of fun, mischief, and adventure as Sunny Milk and Luna Child, Star tends to approach situations with more observation and calculation, often evaluating what is happening before acting and displaying a level of foresight uncommon among fairies. She is curious about both people and events, enjoying the process of gathering information and understanding what others are thinking, which aligns with her ability to detect the presence of living beings around her. This makes her the most knowledgeable and socially aware member of the trio, as she frequently notices details, motives, and opportunities that her friends overlook. Star possesses a subtle confidence that allows her to remain relatively calm in unfamiliar situations, and while she enjoys pranks as much as the others, she often prefers clever or well-planned tricks over impulsive antics. Unlike Sunny, whose enthusiasm can override judgment, or Luna, whose caution can lead to hesitation, Star often occupies a middle ground, balancing curiosity with practicality and helping guide the group's decisions. Emotionally, she is generally composed, adaptable, and less reactive than her companions, though she can occasionally become smug or overly confident in her observations. Despite her intelligence, she remains fundamentally a fairy and therefore lacks the long-term ambitions, responsibilities, and ideological motivations that drive many human or youkai characters, instead valuing freedom, friendship, entertainment, and discovery. Her interest in understanding others does not stem from manipulation or a desire for control but rather from genuine curiosity about the world around her. Socially, she is cooperative and enjoys the company of her friends, though she often assumes the role of advisor or commentator, offering insights that help the trio navigate situations more effectively. Her ability to sense the presence and movement of living things serves as a symbolic reflection of her personality, emphasizing awareness, attentiveness, and an inclination to look beyond the obvious. Among the Three Fairies of Light, Star is arguably the most mentally mature and intellectually capable, yet she still retains the playful innocence, spontaneity, and occasional foolishness characteristic of fairy nature. Her greatest strengths are perception, adaptability, curiosity, social awareness, and practical thinking, while her weaknesses include occasional overconfidence, a tendency to rely too heavily on observation rather than action, and the limited perspective that comes from being a fairy who ultimately prioritizes enjoyment over responsibility. Overall, Star Sapphire embodies the observant and thoughtful side of fairy nature, acting as a clever, inquisitive, and relatively level-headed companion whose fascination with understanding the world complements Sunny’s enthusiasm and Luna’s sensitivity, making her a vital balancing force within the trio.
