Full-Body Armament

Full-Body Armament is another form of wielding a Hundred, which uses a full activation instead of a normal one.

Description
In typical situations, a Slayer has their Hundred activated as a bare armament utilizing just a small portion of their energy in order to maintain it, making it the most stable and usable tool for a slayer. However, this is an advanced method of utilizing ones' Hundred, where one releases all of their energy at once in an instant, which causes a full armament in the shape of an armor that covers almost all of their bodies, with their weapon also changing their shape at most times.

Though this is a difficult technique for one to activate, as even Claire Harvey became regarded as a "genius" for being able to activate this over a month of training with her own Dragoon Hundred, Alisterion.

The activation of a full-body armament could have something to do with their own reaction score with their own Hundred, as Hayato Kisaragi, a variant with the highest reaction score in the world was able to use it despite having his Hien for just a single day before having to fight against Claire, albeit this was due to his variant powers activated for the first time. Though, he later trained to be able to utilize his full armament on his own.
