Ok pg 73 and74 did the animators forget for a second faiy tail was ecchi not hentai because it looks like they were seconds away from crossing the line lol
This is an OVA, so it doesn't really count as the series changing. OVAs should feel free to be ecchier than the actual series. The main character always had enormous tits, so there was always a bit of sex appeal. She also dresses as a maid on their first mission.
