Modest Heroes will consist of three shorts by three different directors: "Kanini & Kanino" ("Kanini to Kanino") by Hiromasa Yonebayashi will be a 15-minute fantasy adventure story of two crab siblings, and will be long. "Life Ain't Gonna Lose" ("Samurai Egg") by Yoshiyuki Momose will be a 15-minute "human drama" showing the love between a mother and a boy. "Invisible" ("Tōmei Ningen") by Akihiko Yamashita will be a 14-minute "action spectacle" that centers on the lonely struggle of one invisible man. Studio Ponoc describes the shorts as "tales of modest heroes of our times."

While he is the subject of the ignorant jealousy of his peers, rumors begin to spread when Shinichirou meets Noe Isurugi—a girl known for cursing classmates, curses which always end up becoming reality. Noe curses Shinichirou as well, but two pits are created when you curse someone, and her curse on Shinichirou comes back to bite her in the form of a raccoon to her beloved chicken, Raigomaru. Despite this, she does not shed a single tear; Noe had had her tears stolen. For Noe to be able to cry again, she would need the tears of another, and Shinichirou knows a person whose tears he wants to take away.
