Hikari is the leader of a mage clan with some cultlike tendancies. She was happily married to one of the protagonists until her brother, the former leader, suffered an unexpected heart attack, which put her in charge long before she was ready for that kind of power.
She grew distant from her husband, partially because she had so many responsibilities to juggle, and partially because he caught her conducting unethical human experiments. The fact that she turned around and started experimenting on him definitely didnât help.
Itâs not like she wants to be awful; She is just stressed, exhausted, and miserable, and her only outlets are power tripping and sadism.
