Well, that's an ending.
Last two chapters were a mess, thought Haruka would be the one dying in the explosion or at least injured but it continued to be a mess.
Kanade father survived unfortunately, shame she didn't kill him and his reveal Kazuma was a "replacement" for the teacher that bailed after mental breakdown, so she could have unrequited love or else eventually Kanade would kill him for her abuse. That's a stretch.
Sawaguchi being alive after accident and brought nothing and apologizing for not helping in a matter of hours after decision was pointless.
Nabatame after her unsuccessful assassination having a comeback and as well realizing Kanade tried to kill her... thought she would cut her respirator... but... meh...
Story was kinda entertaining, could skip most of Kanade masturbating, but it was probably what kept it afloat for simps to follow it.
In conclusion, 4/10. Could be much better with the premise...
After few minutes of thinking, could come up with better ending for the story...
1. Kanade would lure Haruka to the school by calling her (no cops or Ayumi dies) in the same time telling Kazuma to meet her at her house so "they can runaway together" (also, no cops or Ayumi dies).
2. Kanade calling dad to school, for whatever reason, stabbing him just like in story but more badly injured.
3. Kazuma arriving at Kanade house is told she's not there, puzzled but recalling typical for school sounds in the background when Kanade calling him, rushing to school.
4. Before Kazuma arriving to school, Haruka is lured into the classroom where Ayumi is and is locked with her.
5. Kanade set fire to school so she can kill them all in one go.
6. Kazuma arriving at school just when fire started, seeing Haruka and Ayumi through the window rushing to help.
7. Kanade stopping Kazuma on the way, confessing her love and forcing herself on him, gets rejected and she reaches for an fire axe (die together lulz), after struggle he knock her out.
8. Kazuma busting out the door with a fire axe where Haruka and Ayumi is, but the fire reached the classroom and they decide to jump through the window with him cushioning the fall of both with own body.
9. Fire engulfed the school, burning it to the ground with Kanade father trapped in one of classrooms dying cooked alive (yay).
10. Kazuma awakening like in the story with broken arms, legs, ribs and fractured skull.
11. Police finding charred body assuming it's Kanade father, there's another unrecognizable female body nearby in the hall, after briefing with Kazuma telling it's she who set the fire they conclude it was her after all.
12. After recovery, parents with daughter go on a deserved vacation.
13. When family vacation ends, Haruka and Ayumi sleeping in the hotel room, Kazuma going out on the balcony is suddenly thrown out by the blast set off by Kanade.
14. Plot twist, it was Nabatame body that was found in the school and we basically get Cape Fear ending.
Around yandere never relax. Roll credits.
Also, thanks for the scanlation till the very end!
