Hien

Hien is Hayato Kisaragi's Hundred.

Description
Hayato owns a Chevalier Hundred, which manifests a multiple layered black rugged arm protector covering his right arm and is notably designed to be similar to that of a traditional Yamato armor for protection; as well as an enormous katana that has a blade measuring to be a meter in length to where the sword is described as being a zanbatou, which has a number of four segmented parts running along the blade.

Despite having just trained for a single day in using his Hien, it is proven that Hayato can use it to a much greater degree of skill compared to other Slayers due to his status as a variant, as well release a blast of energy from his sword impressing and surprise even Claire Harvey who has been classified as a being a genius.

Afterward, in his match against Claire, Hayato became able to use his Full-Body Armament after his variant powers were activated when he was about to be shot by Alisterion's Buster Cannon, which formed a full-bodied rugged armor. He could even use an N-Barrier and nullified the Buster Cannon, but was soon overpowered by Claire who used her Full-Body Armament.

Forms

Bare Armament
Hien: He owns a Chevalier Hundred, which takes form as an enormous black katana measuring over a meter long similar to a zanbatou and also a rugged arm protector resembling traditional Yamato armor. As a result of his status as a Variant, he is granted the highest aptitude for a Hundred letting him use it to a far higher extent than others.

Full-Body Armament
Due to his status as a Variant, he is able to release all his energy instead of portions of it, letting him manifest a full armor that covers his entire body. Using this grants him an overall increase in his abilities against Claire forcing her to use her own Full Body Armament.

Air Ride
A unique black aerial equipment for Slayers used alongside their Hundred, which provides Hayato flight capabilities whenever required.

Arms Shroud-Enhanced Hien
Due to Hayato and Emilia having the same kind of variant virus, she is able to enhance his Hien using her Hundred through turning it into particles and added it onto Hien resulting in it to grow larger, with red and white aura radiating from the blade.

Second Hundred
Hayato has another Hundred, which he uses in order to perform a Dual Act, where he summons a white katana that resembles his Hien. Dual Act: Hayato is able to perform a rare technique, which lets him deploy two Hundred at the same time, however, at first, he could perform this using his variant powers, but he was soon able to use it without it.
