— Izuna, after losing in Rule Number 10

Izuna Hatsuse (初瀬 いずな, Hatsuse Izuna) is a Werebeast girl and the former ambassador of the Werebeast race to Immanity. After Sora and Shiro forced the werebeasts to join the Commonwealth of Elkia, Izuna was directed by Miko to follow and learn from them. Sora and Shiro have a habit of petting her fur (tail) yet she seems to enjoy it (much to the chagrin of her grandfather). Steph has noted that she actually shares similarities to Sora and Shiro, such as lacking common sense, being arrogant towards others, and being extremely smart and competent at gaming.


Similar to other Werebeasts, Izuna has a combination of animal and human traits, with her having fox-like ears and a fluffy tail. She has dark purple hair and chestnut eyes (black hair and black eyes in the light novel). Her pupils are vertically slitted, similar to those of a cat.

When Izuna uses her "Blood Break" ability, she grows a longer tail, and all fur from her body turns red. She also has a red symbol on her forehead.


She is adored by Sora and Shiro for being extremely cute, and they love petting her fur. Likewise, Izuna seems to share the same fondness towards them and enjoys being petted. She even mentions once that she prefers the siblings' petting techniques over her grandfather, Hatsuse Ino. The younger trio would develop a sibling-like tie. She is still learning the Imanity language and has a habit of saying "Desu" (please/thank you in dubbed anime) after everything she says in an attempt to make it sound more polite.

She mostly exhibits an innocent personality pertaining to her age yet is very competent at playing games to the point of representing the Werebeasts in national games against other races. In the English translated light novels and anime, she has a habit of unknowingly cursing without actually knowing what the words mean.

Before meeting Shiro and Sora, she never had fun in games, as she was trained to win, not to seek enjoyment.



She possesses all the incredible physical abilities found in all Werebeasts as well as the rare Blood Break found in a select few Werebeast individuals (although she is only able to remain in that form for only a few seconds before she risks death).

She has the ability to learn at an amazing rate if what she is learning is game-related as in the case of learning to read the Imanity language from a gamebook overnight while Steph slept (still limited in speaking the language, however).


Despite being considered "mature" among the Werebeasts at the age of eight, she is still naïve in adult-related subjects.



Hey! Hey you, didja kick the bucket, please?
