Enchanter Vol. 5 (manga)

Haruhiko’s enjoying every relaxing bit of the class trip to Hawaii... except for the dizzying battles on the beach, snooping fellow students and Eukanaria’s usual selfish schemes. But he has brand-new skills to master, and absolutely no time to lose! The itty-bitty swimsuits come out and the crushes take off when a giant game of dress-up turns into a complicated play for power. Will Haruhiko swim to victory, or is he doomed to wade in the shallow end forever?
