Hunter Kindergarten, Dolphin Class!

After two years of job hunting, I finally got a job as a kindergarten teacher at a major company! 20 minutes by walking from home! Suspiciously good benefits and a generous salary! I thought everything was perfect. "Teacher, do you know that your class is called Class S?" "...S? Is it like an elite class or something?" "Ehh~ No~ It means the difficulty is S-class." Excuse me? * "Teacher! Noah brought a bomb potion again!" ...Okay, teacher is on his way.
