Keiji Ayatsuki is the head of MOR's R&D department and a playable character in Iconoclast Saga.


Keiji was born into Ayatsuki family who were known for their intellect and magical abilities. Keiji was a gifted child who was hailed as a prodigy and was often compared to his older cousin, Kokonoe. This irritated him, and he made an oath that he will will be known not only as someone's cousin, but as a brilliant scientist. He studied rigorously and was able to make some important discoveries, but Kokonoe was more famous than Keiji and he was known as "Kokonoe's cousin". He didn't care too much about this, until one day the third of Wadatsumi's population was wiped out by a plague. Keiji made a cure that saved a lot of lives, but not the lives of his parents and girlfriend. This made him think about how fragile humans are, and he began researching in new directions. His new inventions caught attention of the MOR, and he was offered the position of the head of R&D department. Keiji agreed and started to create new weapons for them.


Keiji is very similar to his cousin Kokonoe: he can be a rather serious and cynical individual with no regard for emotions, and always strives to complete his missions without fail; however, he can on rare occasions be quite personable, mostly around his creations. But he is somewhat slow to anger and rarely loses his cool. He is rather vain and ready to do anything to gain more fame.


Keiji is a slender young man with styilsh short brown hair and pink eyes. Due to problems with his sight he wears stylish glasses enchanced with some gadgets. He wears a black dress shirt with a red tie, and over it he wears a white lab coat. He also wears black pants and knee-high red boots.

Powers and AbilitiesEdit

Not unlike Kokonoe, Keiji possesses some combat prowess. His forte comes in the form of his grand knowledge of magic and science due to being a member of Ayatsuki family. His scientific abilities are frightening. He can create dangerous weapons from scrap and also uses a portable teleporter device that allows him to use most of his gizmos.
