Chapter 158

Chisaki's Abnormal Compassion (治崎の異常な恩情) is the one hundred and fifty-eighth chapter of Kohei Horikoshi's My Hero Academia.

Summary
"Paranormality" is a never before seen mysterious mutation that quickly spread among people. According to one theory, it was an unknown virus that was spread throughout the world carried by mice and is believed to be the origin of Quirks. However, there is no clear evidence that backs up this theory.

In the present, Kai Chisaki claims that neither Izuku Midoriya nor Eri herself understands the true power behind Eri's Quirk and through extensive research, he was able to successfully extract Eri's power and bring it to its pinnacle; the result is the Quirk-destroying bullet, which has the power to extinguish one's Quirk Factor and return them to normal. Chisaki reconstructs the surrounding area and attacks Izuku with stone columns. However, Izuku's greatly enhanced speed thanks to One For All: Full Cowl: 100% enables him to dodge with ease. Izuku delivers a kick packed with massive strength and sends Chisaki flying into the air. Izuku feels that Eri's power is getting stronger due to her being unable to control it, similar his inability to control One For All when he received it. Himiko Toga witnesses Izuku's strength and is mesmerized by it while Jin Bubaigawara wonders the whereabouts of the Atsuhiro Sako's clone.

In the Eight Precepts of Death's basement, the Atsuhiro clone is held down by Ryuko Tatsuma, who sends the weightless Ochaco Uraraka and Sir Nighteye to the surface, telling Ochaco to get Sir Nighteye to an ambulance. Meanwhile, Chisaki has been sent straight into the air by Izuku's great strength, having been injured as a result, and starts thinking about the past.

The Eight Precepts of Death's boss criticized Chisaki for beating up someone, to which Chisaki replied that he was simply protecting their turf. Chisaki stated to his boss that they must make their presence known to the world, but the Eight Precepts of Death's boss knew that Chisaki had started a venture dealing with Quirk related drugs and had told him not to get involved and while he understood that he was simply repaying the kindness after the boss saved him, he must not go overboard nor must he stray from his path. Chisaki remembers talking to Hari Kurono about the Eight Precepts of Death becoming extinct if they do not do something; Hari replied that the idea of yakuza restoring the underworld is a detached dream. However, Chisaki refused to waver and planned to restore the Eight Precepts of Death to its former glory. One day after having done extensive research on Eri's Quirk, Chisaki brought forth his plan to the Eight Precepts of Death's boss; Chisaki planned on selling the Quirk-destroying bullets to Villains who would use them on Heroes and after a while, the yakuza would distribute a serum that would undo the damage done and restore the lost Quirks to the Heroes. These products would be at a high price. Therefore, with the Villains having the Quirk-destroying bullets, the Heroes having the serum, and Eri in the middle, the Eight Precepts of Death can monopolistically control the market, earning massive profit and eventually emerging from the darkness. However, the Eight Precepts of Death's boss had already refuted Chisaki's plan and questioned his morality regarding humans. The boss advised Chisaki to leave if he was going to disobey their way of thinking. Chisaki did not plan on going anywhere as all he wanted to do was repay the boss for taking him in and despite the boss's refusal, told him to watch from the sidelines as he went through with his plan. Chisaki blamed Quirks for bringing forth Heroes that put the Eight Precepts of Death's boss in a corner and with his plan he could restore the Eight Precepts of Death back to its former glory.

Izuku jumps towards the airborne Chisaki who has healed his injuries by reconstructing himself and tells the fake Heroes to stay out of his way as he slashes at Izuku with one of his claws. However, Izuku evades with ease and knows that Chisaki can repair himself with his Quirk through disassembling and reassembling at a fast rate, but he plans on using the great power of One For All: Full Cowl: 100% to close that gap and beat him before he gets the chance to recover with his Quirk. Izuku charges towards Chisaki and starts pummeling Chisaki's monstrous stone body, shattering it as Chisaki is unable to counter attack. Izuku reaches Chisaki's own body and pummels away. Izuku questions that if he cannot save one little girl right in front of him, then he can never become a Hero that saves everyone.

Ochaco and Sir Nighteye have reached the surface and bear witness to Izuku and Chisaki's battle. Ochaco questions Sir Nighteye's vision about Izuku dying. Sir Nighteye replies that it is the unchangeable future he saw but is surprised that events are playing out differently.

Izuku reaches Chisaki and punches him in the face with enough force that not only sends Chisaki reeling but also breaks off his plague mask.
