Classroom for Heroes, Vol. 3 - Haruyuki Morisawa, Shin Araki

COME TAKE A SOAK IN THERMAE ROSEWOOD!Blade, now surrounded by his 111 friends (including two birds and a dragon), should be enjoying his sweet school life, especially the new mixed-gender hot springs on campus…So why isn’t he?! Well, first, he must compete with the king himself for Earnest's affffections, then a superstrong Guardian appears at the academy on a special mission to terminate him! On top of that, the entire student body gets locked in the bowels of the royal castle for more so-called “practical training.†This ex-hero may be retired, but his adventures aren’t over yet!
