Amagiri Ayato (天霧 綾斗) is the male protagonist of Gakusen Toshi Asterisk. Ayato's main objective behind entering Seidoukan Academy is to find a purpose in life, though later the latter changes to fighting for Julis.
Ayato has both purple hair and eyes. On both sides, the front of his hair reaches just below his chin. In the middle of his face, his bangs droop between his eyes. His hair is almost symmetrical. He wears the traditional Seidoukan Academy uniform for males.
Ayato sports a friendly, polite, and helpful personality with a penchant for ending up in awkward situations. He is indiscriminate as to who he is being friendly to and is helpful to a fault, as well as being a bit naive. However, underneath the soft facade lies a person with an indomitable will who always tries to do the right thing, regardless of the potential trouble that he will get himself into.
Ayato's family runs a dojo that teaches ancient techniques by the name of the Amagiri Shinmeiryuu. He grew up with his father and half sister, though his relationship with the former became estranged when the latter disappeared. He also grew up as neighbors with Sasamiya Saya, who played a role as both his childhood friend and later, his sparring partner.
As a kid, he promised to protect his older sister and would even fight with people who would diss or doubt her. Haruka promised to protect him and even put a powerful chain seal on him, so he wouldn't fight with all of his power.
- Haruka's Seals: Before she disappeared, Haruka had placed three seals on Ayato using her Strega ability, all of which acted to seal the Ayato of six years earlier, preventing him from naturally using all power gained since then. He managed to break the first seal own his own, unlocked the second one during his battle with Julis against the Li siblings, and was finally able to unlock the third one during Team Enfield's battle against Team Lancelot with some training from Madiath Mesa the night before, getting rid of the seals completely. While the unlock requirements for the first two seals are unknown, Madiath states that the key for the third seal was for Ayato to surpass Haruka in strength.
