Ryofuko-chan

Aoki Daisuke is a fresh, new elementary school teacher, eager to help shape and guide his young students. But he got more than he bargained for with Kokonoe Rin! This saucy third grader has knowledge beyond her years, and a deep-seated mistrust and loathing of adults. She will go to any lengths to protect her friends Kuro and Mimi, including harassment, extortion, threats, and sexual blackmail. And yet, with her friends, she is kind, caring, and self-sacrificing. Can Daisuke gain Rin's trust and save her from her dark side without falling victim to it himself?

Ink Nijihara, who does very well in her high school English class, has a crush on her classmate Nao; but as she is both shy and clumsy, she finds herself unable to get closer to him. Furthermore, since he does poorly in English, he does not intend to go to a university, crushing Ink's dreams of going there together with him. Out of the blue, a talking duck who turns out to be a polymorphed (and perverted) wizard exiled from a magic kingdom falls from the sky and lands in front of Ink. He offers her magical powers in return for helping people in need. Ink sees the magical girl transformation as a chance to help Nao with his English without feeling embarrassed about it, and thus she begins her adventures as Magical Teacher Pastel Ink!
