Bofuri: I Don't Want to Get Hurt, So I'll Max Out My Defense., Vol. 5 (Manga)

Word is the next event will focus on large-scale guild PVP, and that's bad news for Maple Tree. With only six members, they're sure to be at a disadvantage-- and the other top guilds are even putting together anti- Maple strategies! Fortunately, the gang picks up two new recruits: Mai and Yui, twin sisters bearing all-strength builds who'll pack quite a punch after a little power leveling. But with Maple evolving into even more of a literal monster, will she be a bad influence on the newbies?
