This is Dark Grasper, posing as a famous idol named Anko Isuna. Sure that no one would take a hint that Isuna-chan is none other than Dark Grasper, but the reason she wore her black Glassgear is to become Twoearle’s ally.
Really, then explain yourself why did you join Ultimaguil where those baddies attack her homeland for twintails?
Meanwhile, Erina is researching about porn magazines for some reason. While I don’t know this research would help her become stronger or hornier at worst, but Erina asking for lewd things would get noticed from the disciplinary committee… if there is one!
Anyways, next week will have Erina being forced by her mother to find a husband. This would be total drama!
