Class 77‑B at Hope's Peak Academy, already known for its oddities, is about to welcome an even more unconventional member: Chisa Yukizome, a former student who holds the rank of Super High‑School‑Level Housekeeper and will serve as their new homeroom teacher. Bright, enthusiastic, and efficient, Chisa promptly tackles the students" troublesome conduct and works to deepen their bonds. Managing a mix of personalities—from princesses and nurses to yakuza figures and extraordinarily lucky individuals—may prove difficult, yet hope"s power can turn any challenge into possibility.
In the meantime, Hajime Hinata, a plain‑spoken pupil from the Reserve Course, yearns for a special talent. One day he encounters Chiaki Nanami, the Super High‑School‑Level Gamer of class 77‑B, who offers him a fresh, hopeful perspective on life. Little does he know that the school"s leadership is preparing a dark scheme centered on him, one that will collapse Hope's Peak—and the world—into ruin.
Zetsubou‑hen follows the everyday routines of the talent‑fostering school while revealing the shadow that lies beneath. As despair creeps into hope, a plan unfolds to trigger the greatest, most dreadful, and tragic event humanity has ever seen, marking the beginning of the end.
