Mason, Chooki

蜂須賀チュウキ

Chooki possesses a calm demeanor. He is the team's top athlete and consistently anticipates challenges.
He is capable of transforming into Lydendor. He characterizes himself as "Tenkai Agility". In his Lydendor form, he wields a short blade suitable for melee combat or extendable via a chain to function as a flail, alongside a shield equipped with three curved blades that he can throw and retrieve. He was the third to unlock Titan mode, which doubles his size; in this state, his shield takes the form of a large shuriken used for both offense and defense.
