Kaguya has a rather carefree personality, as she often sneaks out to visit the human village. She apparently is refined in the art of conversation, but her vocabulary is a bit dated. She is also described as haughty and relatively wild.

Kaguya can has Manipulating eternity and the instantaneous power, Eternity is namely immutability, and it can be said that eternity rejects all change. Things that possess eternity indefinitely do not change, and also cannot be interfered with by things outside of themselves. By using her ability on everything in Eientei, she made it so that living things stopped aging, objects would never break, and food would never spoil. Additionally, beginning from when Kaguya came to Gensokyo, she lived hidden away for a thousand years in the interior of the Bamboo Forest of the Lost without anybody knowing about her. Also, the pure Japanese-style mansion in Eientei can be seen not to have worn out at all, which can be said to have been due to this ability of eternity. After the Eternal Night incident, Kaguya removed the spell of eternity from Eientei, causing objects to break as normal, living things to age again, and food to spoil if not eaten in time. Incidentally, as the Hourai Elixir made by Kaguya's ability of eternity is something that makes the consumer have a "body that rejects all change," it can simply be said to be a kind of maximised, self-healing ability (due to this, it is said that the entire body can recover from just a single hair left intact, as shown in the case of Fujiwara no Mokou). In the last spell card "End of Imperishable Night" which used this ability, it destroyed Reimu Hakurei and the others' spell of eternity, and forcibly called for dawn (End of Imperishable Night -Rising World-, where "Rising World" was a homophone to "dawn" as "yoake" (夜明け)).

On the other hand, Kaguya, in being able to manipulate the instantaneous, is able to alter the needed "instants" and make them her own time. However, whatever she gathers together—since it is made up of many "unrecognisable instants" that cannot be changed—has no means of being known about. For this reason, in manipulating the instantaneous, Kaguya is able to spend "time the same as others'" and "time different from others'" simultaneously. Hieda no Akyuu presented this as "having parallel timelines at the same time". As the instantaneous is the smallest unit of time, time is able to accumulate countless instants. Watatsuki no Toyohime explained that to see time as continuous is due to the inability to recognise the instant.

Since her ability can be said to be the ability to manipulate "complete stop = eternity" and "extreme speed-up = instant", Akyuu also summarised it as an "ability to manipulate time". This seems very similar to Sakuya Izayoi's "ability to manipulate time."

Kaguya is shown to have dark brown eyes and very long black hair in a hime cut style. She wears a pink shirt with many white bows, and a long, dark burgundy skirt decorated in plants and flowers representing the four seasons. Respectively, they are cherry blossoms, bamboo leaf, maple leaf and plum blossoms. Her 5 Impossible Requests are seen floating around her, probably waiting for her order to engage in a spell card attack.}}
