Great Prophecy

 Great Prophecy' (大予言, Daiyogen'') is the thirtieth chapter of the OnePunch-Man manga series.

Summary
Shicchi introduces himself and explains the situation. Before he explains the situation, he warns them that once they start listening to what he has to say, they will be confined to the room until the meeting is over. Metal Bat interrupts Shicchi, stating that he had to skip his sister's piano concert to attend this meeting, and threatens to destroy the headquarter building if Shicchi did not have anything important to say. Shicchi announces that the great prophet, Shibabawa, is dead. Most of the heroes are shocked to hear this news. Zombieman asks whether she was murdered, which Shicchi replies that she just died from choking on cough drops. Superalloy Darkshine asserts that the Association brought them to tell them that they must now prevent disasters without Shibabawa's help. Shicchi states that Darkshine is wrong and that she has always only predicted a fraction of all disasters. Saitama asks Pri-Pri-Prisoner who is Shibabawa. Pri-Pri-Prisoner tells Saitama that she was a great prophet that could predict the exact timing of disasters, such as natural disasters and monster attacks. Finally, Shicchi states that the real problem was that her final prophecy was a note stating earth is in trouble. Child Emperor then tries to make an excuse to leave. However he is only mocked by Shicchi, stating that Child Emperor is nothing more than a child if he does not comprehend the danger of this matter. Additionally, Shicchi states that the disaster is above Dragon and will happen within half a year. Watchdog-man comments that they cannot do much to prevent the disaster. Saitama remarks that the prophecy might come true sooner than expected. Suddenly, the headquarters comes under fire from Skyfolk. Outside the Sky King prepares his attack with his henchmen. However, the Skyfolk are then attacked by an unseen being.
