Ageha is a playable character in the Espgaluda series of bullet hell shoot 'em ups. He is the fastest of the characters. His shot is narrow, and when he enters Kakusei Shikai, his laser's power is increased. He is normally a male, but becomes female in Kakusei Shikai.
At a very young age, Ageha and his sister Tateha
-- a two-year-old and a newborn at the time -- were part of a super-soldier project conceived by their father Jakou
, the depraved king of Shinra
. One of the alchemists in the project, Hiodoshi
, felt pity and helped them escape. He tried to give them as normal an upbringing as possible, but after sixteen years Jakou's soldiers found them, and Hiodoshi was brutally killed. This trauma awakened Ageha and his sister's powers, and with them they managed to defeat Jakou and his army.
Three years after Jakou's defeat, Ageha and his sister had moved to the nation Soma
, where they hoped to live in peace. However, as Soma's scientists discovered the secret behind Shinra's former power and re-started the Espgaluda project, they were once again forced into battle.
