The teacher and principal of this kindergarten! A kind male teacher who truly cares for his students. He wears a patch of a purple rabbit (Mori-usa) on his clothes. Mori-usa is the mascot character of this kindergarten. Because the kids are so chaotic, he sometimes just gives up. "Yeah... Teacher doesn't even mind anymore when things end up like this... ☆◜▿◝"

One of the students at this kindergarten. Red hair with black mesh. Odd-colored eyes, yellow and purple. He has dog ears and wears a hat. "Papa and Mama told me I have to keep this on!"

One of the students at this kindergarten. Yellow hair and yellow eyes. Called one of the "Three Scheming Brothers" by everyone. (?) "Me, scheming? I'm not like that at all! ^^"

He looks cool, but he's actually a bit untrustworthy, so none of the kids like him very much. ("Why though?!" - Vau) ↑ It's because you go out of control so often. Red hair and yellow eyes. He often goes wild in front of the kids. "So, that's actually ██..." (Way too inappropriate lol)

One of the students at this kindergarten. Cute and reliable, but he's one of the "Three Scheming Brothers" along with Root. ("That's unexpected..." - Nanamori-sensei) Pink hair and green eyes.

One of the students at this kindergarten. Characterized by his Kansai dialect! He loves Riinu-kun! (RIINU-KUN RIINU-KUN RIINU-KUN RIINU-KUN RIINU-KUN - Pritz) Yellow hair with lime green tips. Lime green eyes and wears round glasses. He's constantly playing the funny man.

One of the students at this kindergarten. A child shrouded in mystery. Their actions are cute, but sometimes scary... One of the "Three Scheming Brothers" along with Root and Teruto. Apparently lives on Planet Popipapapapipo, maybe? White hair with two black X-shaped hair clips. Purple eyes. Has a bit of a fallen angel side.

One of the students at this kindergarten. Red hair with black mesh. Light blue eyes. Sometimes mentions the phrase "Age Regression Program." (Terrifying...) Loves everyone! Energetic and great at cracking jokes!

A teacher at this kindergarten! Black hair with red mesh. Has ears like Riinu-kun's. ("I'm a lion! ☆" - Rao) Wears a lion patch on his clothes. He's the one who keeps everyone organized and serves as Nanamori-sensei's assistant!

One of the students at this kindergarten. Light blue hair with two mushrooms growing out of it (🍄•᎑•🍄). The biggest airhead of the bunch, and a master of gags! "I'm gonna make everyone laugh a ton!!" ("I see, but please don't say anything weird, okay~♪" - Nanamori)
