Taken from Gods Eater Burst's database:
An Aragami resembling a Kongou with a split face. Carries an electrical charge throughout its entire body: able to discharge electricity and generate lightning. Thought to have evolved after a Kongou received a face-splitting blow. Origins unknown.
When enraged, it generates lightning by pounding both arms. As it's capable of wide-ranging attacks, aim for its head and arms with a gun.
