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."

The Yamada sisters, Kyou (15) and Asu (9), are students studying in secondary and primary schools respectively. Their mother passed away and their father ran away after incurring gambling debts. Despite the difficult circumstances, both of them decide to overcome the unhappiness and welcome their days with enthusiasm and pride. Fortunately, with the change in the law system several years ago, Kyou is able to study and simultaneously take temporary jobs (such as distributing newspapers and tutoring) to make ends meet. On the other hand, Asu takes charge of household chores, prepares meals, and manages the finances to assist her older sister. Surrounding them are also good and kind neighbors such as the novelist, Saegusa-san, and the aunt at the public bath who watch over them. Although life is difficult and at times painful, the sisters are happy to have each other. (Source: ANN)

A mysterious device crashes on planet Earth, causing a wildfire near where Gohan Son, Kuririn, Bulma, and Oolong are camping. Unable to fully save the forest, they decide to use the Dragon Balls to restore it to its previous condition. A few days later, a group of unknown warriors plant a seed where the mysterious device had crashed, sprouting a colossal tree that destroys the forest and neighboring cities in the process.

North Kaio contacts Gokuu Son and tells him that this tree is the "Shinseiju"—a tree that absorbs all the nutrients in the planet and leaves it a barren wasteland, all the while growing a mighty fruit capable of providing incredible power to anyone who eats it. After learning of this, Gokuu and his friends try destroying the tree before it is too late, but that may prove to be more difficult than they had previously imagined.
