Ikaruga, Natsuki

斑鳩夏生

He is a former student of The Academy, an elite urban institution reserved for the brightest minds. After being expelled, he returns to live in the small coastal town that was his grandmother's home.
Having lost both his mother and his leg in an accident at a young age, he is overcome with terror when forced into dark, silent spaces.
To raise the funds for an advanced cybernetic leg, he joins a scheme to salvage hidden treasure from his grandmother's sunken storehouse.
