Maki’s murder confession turns out to just be a sick joke, as she amends her self-introduction as someone with a “terrible personality”, which seems to be enough for Sonozaki. With that, there’s nothing left to do but go home and prepare for the school day. But someone—who from the OP is clearly the seventh Kiznaiver—is watching them, seemingly approvingly.
Tenga decides the best place for him to crash is at Agatas, to make sure “random people don’t do random things” to him, which would now affect everyone. He’s surprised to learn not only are Agata’s parents away on business, but Chidori lives right next door to him.
As romantic a scenario as that might sound, especially after the two’s confessions, Chidori makes it plain (though not veyr convincingly) that her love for him was in the past.
Agata naturally finds a way to make her pity him by asking whether he should just forget she said anything, worried “unnecessary things” would make things awkward. While he made a smidgen of progress last week, this kid still has a long way to go as far as making connections.
The entire day is marked by the Kiznaivers all feeling a sudden jolt of shared pain, but when they’re all together, they learn it’s the pain of the seventh, whom they’ve not yet met. Once they figure out there’s a seventh, Sonozaki assigns them their next mission: find him.
I’ll also say that just because all the Kizzys are connected through pain doesn’t make them suddenly best friends at schol. Yuta doesn’t like “weirdos” like Tenga, Nico, and even Chidori hanging around him, nor do his girlfriends. But this is all about adaptation. Yuta can like it or not, he’s in a different clique now.
Through process of elimination, the six determine the seventh is Hisomu Yoshiharu, the only classmate not at school. They show up at his Ayanami Rei-style grimy apartment and use his own cries from their shared pain to flush him out. What follows is a breathless chase across town, with Tenga continuatlly punching Yuta so Hisomu will cry out and they can locate him.
When Chidori and Nico decide they’re tired of feeling the pain of others getting punched, they ask Tenga to hit them, but are stopped by the neighborhood watch ladies, allowing Hisomu to give them the slip. Agata, however, keeps following him, meets him on a bridge over a highway, and tells him he wants to “make a connection,” as Sonozaki assured him all humans wish to do.
Hisomu responds by asking Agata to jump to his death. Agata and Tenga realize jumping is the only way they’ll keep him from running off again…but Tenga can’t do it, and Agata beats him to it. He ricochets off a box van and falls into a MINI convertible, bloodied and concussed, but alive.
All six other Kiznaivers felt his pain, including Hisomu, who we learn is a masochist who loves and gets off on pain, to the disgust of Maki and Yuta but the fascination of Nico. The mission is complete, and now all seven modern deadly sins (Hisomu’s being “immorality”) are now represented.
While at first I was fuzzy on why they drew out the intro of the seventh member to the third week, as the episode ended I acknowledged the fact that this guy reacts the opposite way to pain as everyone else, making him exceptional among exceptions.
Sonozaki declares in an address at the institute where she works that obtaining the “true connection” involves those “tripped up by sin” who “struggle in the darkness” and find the true power od their bonds…even if those bonds were artificially established.
I wonder what their next mission will be, beyond the overarching task of surviving the Summer. I’m also a little apprehensive that it’s implied that will be no cakewalk.
