this is akumu, the last memeber of 1-X (and only made cause it's october)
akumu is just a big cat with a nightmare quirk, nothing more, nothing less
she is a bit late because her mom has some medical treatment in another country, but now she is coming to school (she is also the tallest by far by being exactly 3 meters tall)
like said before she is just a big cat (also don't try to fight her, unless your oc has Zero fears, and even then don't fight her, she can weaponise her own fears, and those of others)
