The headmistress has had enough. After watching the legendary Supreme Five Swords get demolished by a single opponent, she's forcing them on a mandatory vacation to build teamwork and recover their pride. There's one catch: the budget somehow stretched to include a sixth person, and both Rin and Mary are pushing hard to bring Nomura along. What should be a relaxing getaway becomes anything but. The Five Swords are notorious for their competitive nature and clashing personalities, so throwing them together outside school walls creates immediate chaos. Add in the question of who actually gets that sixth spot, and the trip transforms into a contest of wills disguised as a bonding exercise. This OVA captures the series' signature blend of over-the-top action and comedy, letting the cast's dynamics loose in a lower-stakes setting. It's pure character fun for anyone who's already invested in these fighter girls and their messy relationships. Nothing revolutionary, but exactly what fans want: more time with characters they enjoy watching clash and grow closer.
