Long Summary[]
Fubuki, despite her injuries, tries to join the battle against the remaining monsters of the Monster Association to support her sister and the other heroes. However, Bomb intervenes, concerned for her safety. After observing her, Bomb remarks that Fubuki and Tatsumaki share similarities, which Fubuki promptly denies.
On the battlefield, the heroes are successfully fending off numerous copies of Black Sperm. The Council of Swordmasters and Spring Mustachio arrive to bolster their efforts. Noticing that the heroes are holding their ground and proving challenging, a Black Sperm clone seeks help from the Homeless Emperor, who is casually seated amidst the rubble, watching the fight unfold. Homeless Emperor declines, stating it's a race to hunt the S-Class and challenges the clone to prove itself, which frustrates the clone before it departs. Homeless Emperor then plots to eliminate Black Sperm after the monster multiplies to its maximum and threatens humanity with sheer numbers, while he continues to observe the battle as Black Sperm struggles against its foes.
Genos successfully brings Tanktop Master to Fubuki and urges her to heal him before returning to the fight. Both Fubuki and Bomb are shocked by Tanktop Master's injuries. Fubuki doubts her remaining power will suffice, while Bomb wishes to contribute his strength. Fubuki suggests they try combining their powers. She places her hand alongside Bomb's on Tanktop Master, using her telekinesis to channel their energy into healing the wounded hero. This effort proves somewhat effective, as Tanktop Master begins to recover, albeit slightly. Suddenly, Garou, now monstrous in appearance, emerges from underground to confront Fubuki and Bomb. The elder martial artist loudly calls for Bang, alerting his brother and the others to Garou's presence. While Bang is occupied with fending off Black Sperm's clones, Atomic Samurai advises him to leave the area to him, which Bang gratefully accepts. As Bomb readies himself to fight Garou, he instructs Fubuki to stay back.
