Despite this his stepfather didn't leave her and loved Aito as if he was his own son, and helped with accommodating his son with the necessary things for a merman to grow.

Sometime later Aito's village was visited by Chirisegyo Sancho who was looking for new recruits for her group, she was introduced to Aito but she considered him to young to be part of her group but could see great potential in him and recommended that he go to the Darkaria Academy which in return would give his family protection to which he, and his parents, agreed to.

After being enrolled he first meet Benjiro Yukedasai when he was being bullied for being a bastard child, which actually scarred him, and Benjiro fought back the bullies to which Aito thanked him. From then on they both became good friends and later they meet Chouko Fuchihiro who steadily became friends with them. After graduation they went into the Darkaria Academy and became soldiers under Ayaka Hebiga and Kagami Higurashi.

Appearance
Aito has tan skin, mint eyes with short, messy pink hair that has three ahoges, two short and a long one that curls in front of his forehead and bangs. His most distinct features are his blue fins with one being on each ear, forearm, back, calves from which he can stick out poison barbs out of the stalks, he also has fins attached between his fingers. He wears a modified Darkaria Military outfit that takes the form of a sleeveless scuba suit that exposes his toes and heels while having slits to let his fins slip through. He also wears fingerless gloves that come up to the base of his fingers.

Personality
Aito is always shy when meeting new people as he's afraid of what their personality will be if they find out about him being a bastard child, in which when is mentioned he freezes due to being self conscious about it, though when finding out about how they feel about the truth he'll be more confident around them or will try to avoid them completely. In battle though he has a serious side and is much more confident and focused, so much so he doesn't flinch when mocked but does still freeze when his status is brought up.

Weapons
His main weapon is poison that's stored in a poison sack inside his body and is secreted by poison barbs inside the stalks of his fins and even if slightly scratched the poison will make it's way into the body and cause vomiting, high fever, and eventual organ failure resulting in death.
