Personality: Kokkaku has a rough and tough personality, something that causes issues with other people. He is rarely seen having a good time at all, getting into fights with other students if they push him too much.
Mana Class: B-
Tokubetsu: Crowned Skeleton.
It is an Intramural type, the abilty to change his anatomy to an extent to improve his prowess in mana. The ability only takes effect whenever his bones become damaged, given that the nature of the abilty is relatively passive to an extent given that he doesn't need to manually activate it since it is always technically active.
However, Kokkaku does have the unique ability to crack his own bones manually by specific flexations in his body powered by mana. Essentially, he focuses his mana to a certain point, causing great stress in that part of the body until the bone eventually cracks.
Now, this works because Crowned Skeleton causes his body to generate a very large amount of calcium, and the ability to direct it to heal any damaged bone. For a limited time, the area that was healed by the ability will gain a boost in physical strength. The bigger the bone or amount of bones, the bigger the boost. The more damaged the bone is, the more the body uses resources to heal. If it is big enough damage, the bones will actually pierce the skin, as the body will go above and beyond to make a stronger bone. When the bones pierce the skin, the ability allows for the shape of the bones to be manipulated for three seconds by his own mana.
However, after the time is up, the bones will harden completely outside the body. This does cause pain to Kokkaku, the bigger the bone, the more pain. This is why he tends to not damage the bones too much and will create small designs outside his body. His mana does thankfully mitigate some of the pain though.
