In Getsuyoubi no Soratobu Orange's animated universe, there's a motley crew of characters including extraterrestrial teachers who look like oranges, watermelons, and a dog named after fermented soybeans. Yoshino is high-strung and determined, while Tsuka-pon acts as the citrus consultant. Natou is a loyal dog, "Senpai" is usually asleep or wandering, Manaka loves animals and has bushy eyebrows, and Nanami (Nacchan for short) rides her bike to school every day. This eccentric and enthusiastic group of characters create a whimsical and charming world.
