Stringendo: Angel-tachi no Private Lesson

Tomohisa and Endou aren't either so handsome or ugly; they are just normal boy students. They're looking at Mizuho, the senior student, and Mikura, their classmate. Mizuho is a returnee student, and she attracts all the students by her beauty. Mizuho notices their eyes, and she gives Tomohisa a suggestive look. One day, Tomohisa finds a note in his desk. It says, "I'm waiting in the ladies' room on the third floor". He goes there and finds Mizuho is waiting for him... The next day, Tomohisa can't help recalling the event the day before. He happens to find that Endou is gone, and also Mikura, whom he loves secretly, is missing, too. He's afraid that they're doing things. However, exactly, they're doing things on the fire escape.

Directed by Seto Yuuki, Hideki Araki, Stringendo: Angel-tachi no Private Lesson leans on a strong ensemble — Noriko Rikimaru, Oma Ichimura, Harumi Asai — to carry a story that balances spectacle with character.

The series landed with audiences for its craft and performances, and remains one of the most talked-about animation titles of 2006.
