The situation of the battle within Psykos’ prison continues to escalate as Tatsumaki persistently confronts Tsukuyomi’s henchmen. Meanwhile, Fubuki is left in despair as she “loses” Saitama at a crucial moment.
Now, One Punch Man chapter 177 has been released, revealing the following developments in the story:
1. Tsukuyomi’s henchmen turn the situation by administering a drug to Fubuki

Previously, many readers of One Punch Man speculated that Tsukuyomi’s henchmen would have the advantage to overpower Tatsumaki. However, the truth is that the advantage lies with the drug that hinders Fubuki, who has been relying on various daily enhancement pills. This drug seems to be a stimulant based on the reactions of those present.
Tsukuyomi’s henchmen activated the drug to disable Fubuki, Tatsumaki, and Psykos simultaneously.
Tatsumaki suspects that a spy named Tsukuyomi has infiltrated Fubuki’s inner circle. Ironically, this spy turns out to be a new member of the Blizzard group.
2. Saitama has taken down all the monsters
After defeating Fubuki, Tatsumaki, and Psykos, Tsukuyomi’s henchmen opened the prison to let the monsters from the Quasar level in, intending to eliminate the three girls. This caused the Blizzard team members to panic as they realized they could not escape without Fubuki’s help.
However, a surprising event occurred. The monsters that entered were immediately subdued by a swift punch from Saitama, who inadvertently dropped into the prison at that moment.
Not only did the Blizzard team panic, but Tsukuyomi’s henchmen and their allies also struggled to survive in this chaotic moment.
3. Tatsumaki defeats Tsukuyomi’s henchmen and protects Fubuki
Seeing that Tsukuyomi’s henchmen were about to overpower Fubuki, Tatsumaki quickly intervened and began her counterattack.
Initially, she managed to intercept the signal emitted by Tsukuyomi’s henchmen and locate the source of the drug affecting her sister. Then, she promptly transformed it into a thorny vine that ensnared the henchmen. Not only that, Tatsumaki even hurled it back at Tsukuyomi’s side.
Afterward, Tatsumaki decisively eliminated the henchmen in a single swift move that shattered the prison’s structure, allowing her to rescue Fubuki while simultaneously warning Psykos.
Before this situation, Tsukuyomi’s henchmen had attempted to infiltrate the Blizzard team to cause chaos, but they were caught off guard by Tatsumaki.
4. Tatsumaki scolds Fubuki and her team
After rescuing Fubuki, the Blizzard members wanted to approach her, but Tatsumaki immediately intervened.
Tatsumaki felt that Fubuki’s constant reliance on the larger group only made her weaker, which could lead to detrimental consequences if they were to face danger again. An example of this situation just occurred. Tatsumaki demanded that Fubuki cut off ties with her friends, as it would be incredibly dangerous if she continued to rely on their support. The power dynamics in this moment could be significantly skewed.
After the Blizzard team expressed their disagreement with Tatsumaki’s stance, she expressed her displeasure and insisted on her demands. She even suggested that the Blizzard group should consider not depending on others to avoid becoming a liability.
5. Saitama intervenes to stop Tatsumaki
Saitama also pondered what Tatsumaki was doing was going too far, especially if it was merely to instruct her sister and to reflect on why heroes had to battle each other.
From this moment on, we can speculate that a showdown between Saitama and Tatsumaki may occur, similar to what has been seen in the webcomic version.
