Monaca Towa (塔和 最中 Tōwa Monaka; usually spelled as モナカ Monaka) is the main antagonist of Danganronpa Another Episode: Ultra Despair Girls.

Monaca is the true leader of the Warriors of Hope. She is in charge of the "Mage" class and has the title of Li'l Ultimate Homeroom (超小学生級の「学活の時間」chō shōgakusei kyū no “gakkatsu no jikan” lit. Super Elementary School Level Homeroom Period).

In combat, Monaca controls the "Mage Robot Black Suspirian", a large mecha which incorporates the weapons of the other Warriors' robots.

Monaca and Warriors of Hope's advisor Kurokuma lost their fight against Komaru Naegi and Toko Fukawa in chapter 5. Her plan to make Komaru Naegi into the Successor of Junko Enoshima utterly failed as she failed to persuade Komaru to destroy the Monokuma Controller.

Monaca returns in Danganronpa 3: The End of Hope's Peak Academy - Side: Future, dressed up as Junko, participating the Final Killing Game by controlling a robot under the guise of Miaya Gekkogahara.

Monaca has given up becoming the second Junko Enoshima claiming it that the Servant's attempt to mold her into the perfect mastermind had the opposite effect on her. She states that her appearance in the game is to just observe Makoto Naegi. After revealing all of this, Monaca travels to space, claiming she had grown bored of Earth.

Monaca appears as a cameo in the 30-minutes long OVA, Super Danganronpa 2.5: Nagito Komaeda and the Destroyer of the World as a part of Nagito Komaeda's imagination world.
