As Kyoichi digs deeper and tries to find evidence of Nobuto's murder at Reika's apartment, Tetsuo and Kasen secretly scheme to thwart his investigation…but the supposed lady-killer has plans of his own-a secret date with Reika in hopes of revealing the cracks in her parents' plotting. But now that the Tosus have Kyoichi's address, their plans to frame him for the murder can move ahead…until someone shows up whom they don't expect.

Haunted by the horrors of a bloodbath he devised, Tetsuo is crushed by guilt. With his village now reduced to ruins, Tsukuyomi gives Tetsuo an ultimatum-to die by the sword, or to avenge Tsukuyomi's fallen brothers and sisters by fighting Kubo head-on. In a final showdown of brains versus brawn, Tetsuo must employ every last trick up his sleeve to defeat the monster behind the massacre and reunite with his family.

To woo Reika and gain her cooperation, Shin tricks her into taking a vacation with him…except Reika finds out he isn't who he says he is. Fueled by the death of her friend, her thirst to uncover Shin's crimes leads to a deadly situation. Meanwhile, Tetsuo and a so-called ally frantically attempt to track them down and rescue Reika…except all they find is a horrifying scene.

With all that Tetsuo's seen, he knows far too much. The gang goes to extreme lengths to ensure Tetsuo's lips are sealed by blackmailing him and getting it all on film. However, the drama club veteran strikes back by making fake footage of Nobuto where it looks like he's still alive…but it's all for naught unless Tetsuo can somehow hack into Nobuto's social media account. With time running out and not many leads to go on, Tetsuo comes face to face with a stranger who wants nothing more than to kill him-and would, if only he knew who he was.

With their house bugged and under surveillance, Tetsuo hatches a plan to divert the suspicions of the gang…but not all of them buy it. The family now caught in a lie, Kyoichi pulls out all the stops to force out a confession from one of them…and he's not above abduction or murder. But just when all seems lost, Tetsuo forms an unlikely partnership, plunging him straight into a world of violence.

Concerned for his daughter, Tetsuo tags along on her date with two boys in hopes one of them will be around to protect her if he's sent to prison. Little does he know that one of them works for the gang…and both of them know what he's done. Increasingly desperate as the gang ramps up the violence in their plans surrounding Reika, Tetsuo considers handing himself in to the police…until an unexpected ally promises to help take down the gang once and for all.

As the gang rolls into the village to take Tetsuo's head and the village's wealth, Kenshin lies in wait, ready to detonate his makeshift bomb and get revenge for his father. Refusing to let his family be pawns in the village's cult, Tetsuo plots to rescue Kasen and Reika and escape before the gang kills them all. However, after he witnesses something truly vile, he's fully prepared to scrap his humanity and embrace his inner monster if it means saving his loved ones.

A young Tetsuo opens his heart to Kasen, beginning their relationship, but the constant harassment from her family is ruining their lives. And when they try to do things the village's way, it only makes matters worse. If they're determined to spend their lives together and get married, they'll have to fight back by devising a plan as insane as the people of the village itself.

Tetsuo Tosu is a typical father whose biggest worries are his job and his rebellious daughter, Reika. That is, until he finds a bruise on her face. His worst fears come true when he finds out she has a secret boyfriend...and he's part of a crime ring that's using her to steal her grandparent's wealth. If that wasn't bad enough, the thug catches Tetsuo snooping around and threatens to kill Reika as soon as she gets home. Fueled by fatherly instincts, Tetsuo murders the man...only for his wife to walk in and witness what he's done. Now with a corpse to hide and a crime ring hot on his tail, Tetsuo must resort to his love of detective novels and his wits to stay one step ahead of a grim fate...
