Hagane-kin
Hagane-kin (Literally meaning "Steel Muscle") is a powerful technique created by Tosen, it's an ability that allows him to highten his physical stregth greatly using a certain method. With his control over his moleculs and cells and his skill with Life Return, Tosen can weaken and slightly damage his muscle's tissue, after doing so Tosen would use a certain technique called The Transcendent Mind in conjuction with Life Return to greatly excelerate his healing, completely healing his damaged muscle's tissue and making it stronger then it was before giving Tosen a higher level of strength. After repeated use Tosen can gain monstrous and superhuman strength and becomes very bulky. Using Life Return he can return to his normal state if he wishes to.

Using this technique Tosen can become exetremly powerful and strong, he also becomes very agile and fast thanks to his enhanced Leg's strength, easily capable of superhuman feats such as shattering rock or throwing buidings and such, his mucsles become exetremly hardened as if it was made of steel.

Tosen can use this ability in conjuction with another technique of The Transcendent Mind that allows him to remove the limiters on his muscles and unlock it's full power making him incredibly and overwhelmingly powerful, to a level that rivals or might even exceed that of a highly skilled Transcendency user.
