Chapter 69

"Monster Cells" (怪人細胞, Kaijin Saibō) is the 69th chapter of the One-Punch Man manga series.

Summary
Iaian, Okamaitachi and Bushidrill are waiting outside discussing about Garou's hero hunt, while their master Atomic Samurai is attending a meeting with the Council of Swordmasters. At the meeting Atomic Samurai asks the council members for help in catching and killing Garou in worries that Bang might fail and die. The council members agree, except Haragiri who mocks Atomic Samurai's plea. Haragiri proceeds to show them the Monster Cells and reveals he had received them from the Monster Association and transforms into a Mysterious Being himself. Haragiri then orders the others to eat the cells or he will kill them, but Atomic Samurai cuts him first, killing him.

Through his robot Bofoi questions Orochi and Gyoro Gyoro about their goals and while they tell him destruction is a natural part of a monster's instincts it's not their end goal.
