S0E20: Re:PETIT ~Starting Life in Another World From PETIT~ 9: Conquering the Watermelon

Subaru appears at a beach (reference to fanservice episodes), he compliments Crusch’s and Rem’s swimsuit accordingly. Rem suggests that they play Suikawari since they are at the beach. Crusch was the first to try and she claim to be able to hit the watermelon in one swing. Rem is up next however she used her watermelon designed Flail instead and smashed the watermelon. Anastasia popped in and expressed her disappointment for not being able to sell the ruined watermelon.
