Hiro never bothered to cover his tracks that well, and so it was only a matter of time before a SWAT team showed up. In their attempt to capture him, Shion and her grandmother are killed, and the ostensible sociopath, who has chosen them as tethers to his humanity, is clearly very upset and guilty about that.
The police empty clip after clip into him but of course cannot penetrate Hiro’s skin, and he’s able to escape with Shion and her grandma and, I assume, heal them. Still, he leaves them behind, with words of apology, and will likely never let them get in harm’s way again—which means never coming near them again.
It’s a busy episode of Inuyashiki that checks in on just about everyone, even a random cop duo who hope to catch Hiro soon. But its focus is on Ichirou’s daughter Mari, who gets some welcome development beyond the thin outline we’d gleaned thus far of a girl ashamed to have such a poor, pathetic old-looking man for a father.
Turns out that was not nearly the whole picture. Mari’s grades aren’t great, and isn’t that interested in going to college. Instead, she wants to strike out as a mangaka, utilizing a craft she’s honed in secret since elementary school. She’s motivated by her neighbor and classmate, the rich and entitled son of the famous mangaka Oda, and she resents that he’s trying to follow in his footsteps simply because it seems like the natural thing to do.
Meanwhile, Ichirou continues to explore and refine his abilities with the help of Andou, another classmate of Mari’s, and it isn’t long before she spots the two walking and talking together. She stalks them, and dismisses the wild (and hilarious) theories that initially enter her mind (Andou is asking for permission to pursue Andou; her dad is into younger boys; Andou is his bastard son).
She keeps following them, watches them go into hospital rooms, then Googles the “miracle worker” who has saved over 120 lives. Then she sees her father launch himself into the sky like a rocket, and nothing will ever be the same.
By that, I mean Mari immediately starts to think of her father in a different way. Not much time is spent on her processing what she’s seen—it would understandably take some time—but when her mother confronts her on her low grades and insist she abandon the manga hobby and go to college, expense be damned—Ichirou walks in and immediately takes her side.
Granted, Ichirou probably has no idea Mari knows anything about his abilities, so there’s no leverage at play here. Indeed, a pre-transformation Ichirou may have taken his wife’s side instead, because he struck me as a bit of a pushover. But not now. Now he’s willing to let his daughter embrace her dream, because he wants her to be happy.
As for Shion and her Grandma? They’re alive and well, in a new apartment, receiving payments from “him.” He healed them, but apparently could not wipe their memories. My money is on Shion trying to reach out to Hiro again, perhaps to her peril…again.
But being apart from Shion, her grandmother, and their quiet, simple life, not to mention the reason he had to leave it, has an immediate and strong negative impact on Hiro, who slips back into his old homicidal ways. The ones he cares about may still be alive, but it doesn’t change the fact that the police killed them, obviously lacking the knowledge he could repair them.
Had the police left him alone (whether that was the right thing to do or not), he may have continued on his peaceful course. But now he wants revenge, and to lash out at those who dared hurt Shion and her grandma. So he heads to the station and starts systematically slaughtering every policeman he sees—including the two cops we saw earlier.
When he’s done inside the headquarters, he goes outside to find a huge force waiting for him. A sniper knocks him down, and SWAT teams riddle him with bullets anew, but they can only slow him down; they can’t stop him, or really even hurt him. Even when “unconscious”, his defensive systems deploy and eliminate all threats with grim efficiency.
All of this unfolds before the video cameras of the media, which it seems Hiro doesn’t kill. Indeed, he leaves one defiant policeman alive so he can witness him killing all the other police around him, to prove to him he will always win in the end.
But because those cameras are capturing him, Ichirou and Mari are watching on the news, and Ichirou doesn’t see the boy who fought to protect Shion and her grandmother, or saved as many lives as he killed (though he’s now clearly “in the red” again). Ichirou just sees a butcher only he can stop.
