Profile

"Don't let it activate its sword, and if it already has… just don't get cut."

A potent humanoid living Ether, initially observed in the Laketown Hollow and documented by the Third Investigation Team of the Hollow Investigative Association. The exact correlation between these living Ether beings and the downfall of the lakeside town known as Blaise remains uncertain. Due to their immense power and formidable fighting style, the HIA has labeled them as highly dangerous and advises novice Investigators avoid direct confrontations with them. "Don't let it activate its sword, and if it already has… just don't get cut." —Excerpt from interview with an Investigator on the variety show "Teach Me, Senpai!"
