Ralsei

A Darkner who calls himself "The Prince of Darkness". He is the gentle and selfless third hero of the prophecy who is kind to everyone and is a pacifist. Ralsei is a short Darkner that resembles a anthropomorphic white goat. He has white fur, with an unkempt tuft on top of his head, two floppy ears, pink eyes, and pink horns. Ralsei wears round green glasses, a pink scarf, and a long, green robe with a black heart in the center, and the lower sweep appearing tattered. His arms are usually hidden beneath his robe, so in battle his scarf sometimes acts as an arm and and can lift his hat to use an item. Occasionally, he reveals his arms and the robe's long green sleeves, such as when using a spell. Sometimes he is shown wearing a green pointed hat.

Ralsei is noted to be similar to Kris's adoptive older brother Asriel in appearance, but the true relation between Ralsei and Asriel is unknown. (It is also noted that Ralsei is also an anagram of "Asriel") Ralsei is kind, considerate, and quick to apologize if he thinks he has upset someone. He is also gentle and believes that FIGHTing is unnecessary, favoring pacifism in battles while leaving the final decision to Kris. However, he himself makes an exception to this rule if an enemy is inherently hostile and cannot be SPAREd like Titan Spawns.

Ralsei is affectionate, and loves both giving and receiving hugs. He once hugged the Dummy to "test it out", can perform Heal Prayer with a hug and ask Kris to hug him instead of the Dummy. Being complimented or given affection easily flusters him, and he is often self-conscious, citing this as the reason he concealed his face by wearing a shadow-casting hat.

Ralsei is reluctant to get angry. At most, he appears disappointed when Kris or Susie act mean. Ralsei is somewhat naive and innocent, as he readily forgives King when he feigns surrender, but learns to not always be so trustful of others after King's ambush.

Ralsei cares immensely about his friends, and is willing to protect them with his life, and to take any pain on behalf of them. He also supports others establishing friendships, as he favors helping Lancer despite his status. Believing that his purpose is to make Kris and Susie happy, Ralsei sometimes worries that his opinions or desires that do not directly benefit others are "selfish". This guilt leads him to leave his room in his castle unfurnished, as he thinks that there is no reason for him to have anything personal. He also considers friendship to be a responsibility he cannot fully fulfill as a Darkner, which brings him sorrow, yet he views even this sorrow as selfish.

Ralsei enjoys baking cakes, especially for his friends. Additionally, he is fond of dressing up. Ralsei is capable of singing, as he sings a few notes of The Legend. He also appreciates gifts, as he cuddles a plush if Kris gives him a gift in Cyber City, which causes him to want more plush toys.

Ralsei is also responsible, as he encourages Susie and Kris to do their homework and emphasizes the importance of education. If tasked with unfamiliar situations, he prefers to read instructions.

Aware of the prophecy's tragic ending, Ralsei makes efforts to prevent it from happening by only disclosing select parts of the prophecy and being kind, informing Kris in Chapter 1 that kindness may change the outcome of their adventures.When he discovered that the prophecy tapestries within the Dark Sanctuaries remained unchanged despite his efforts, he became overwhelmed with stress and hopelessness, finding it difficult to feign a smile to hide his fears. His hope is renewed by Susie at the end of the Chapter.

Ralsei refuses to curse, often being hesitant to do so or replacing vulgar words.

When faced with absurd situations, Ralsei sometimes ends the interaction by saying "Okay". Ralsei occasionally uses British or Australian English words such as "lift" to refer to an elevator, and "fancy" or "chuffed" to refer to liking something. Being a Darkner, Ralsei can only thrive in Dark World and can't interact with things in Light World. He uses his scarf as a weapon and it is able to act like an arm as well.

Ralsei's spells are support-type spells. Like "Heal Prayer" for healing his allies, "Pacify" for making enemies asleep, "Fluffy Guard" for shielding his allies and "Reviver" for reviving his downed allies. He is shown to be able to levitate and use fire spells as well.

Similarly to other Darkners, he is very knowledgeable about the Dark World, and has some knowledge of the Light World as well. At times, Ralsei informs of gameplay mechanics such as the SOUL's function, Controls, Recruits, knows which equipment can be given to other party members, and reminds Kris to SAVE. He has occasionally written this information in books.

Uniquely from other Darkners, Ralsei is capable of sensing a "dark presence", which often motivates him to transfer into another Dark World on his own. He has complete knowledge of the prophecy, though he did not choose to bear it.

Unlike other Darkners, Ralsei is compatible with all of the other Dark Worlds, as he doesn't get turned into stone in the Dark Worlds he traveled in.

Other than these, Ralsei is great at making cakes. </Powers and Abilities> Ralsei is Darkner who lived in Castle Town in the Dark World of Hometown's school closet. He have lived alone for a long time and calls himself the "prince" of Castle Town despite not having subjects.

Ralsei gets to know about the prophecy of Deltarune at some points, and he awaits for the two heroes mentioned in the prophect to come, and Ralsei himself is the third hero in the prophecy. The prophecy refers to Ralsei as "The Prince from the Darkness.

One day, when two students in Hometown school named Kris (The human hero in the prophecy) and Susie (The monster hero in the prophecy) fell down in the school's Dark World, Ralsei greeted them, saying that both of them are two heroes from the prophecy. Susie, however, doesn't care about being a hero in the prophecy and chooses go on her own way. Kris, however, chose to believe in the prophecy and they accompany Ralsei to seal the Dark Fountain in the Card Kingdom Dark World. During this, they met up with Susie, who is minding her own business and ignores Ralsei's words about being nice to the Darkners there. At one point, Susie chose to join Lancer, who is the prince of Card Kingdom. After the tag battle of Kris and Ralsei and Susie and Lancer, Susie decides to rejoin Kris and Ralsei and be a hero of the prophecy. And Susie began to try ACTing in battles alongside Kris and Ralsei.

Kris, Susie and Ralsei would go on multiple adventures to seal Dark Fountains in many Dark Worlds. However, Ralsei himself actually doesn't tell Kris and Susie about the full version of prophecy, as he chose to not tell some parts of the prophecy, like about the Titans and the final part of the prophecy. Susie angrily confronts him for keeping things secret from her and Kris. Ralsei breaks down and cries as he tries to explain himself. He admits that he knows everything about the prophecy, including how it ends, and had been trying to prevent Kris and Susie from viewing the final part. The two subsequently make up when Ralsei promises to be more honest.
