looking for horror? manga (solved)

[EchoGirl]

It was about a psycho female teacher (not koakuma kyoshi, pov/mc was a male student with glasses), that killed a classmate who attempted to assault her, i think the title had a stutter/repeating words like de-de-de or something

 

[hypoprepia]

dead dead demons dededede destruction? i havent actually read it but it seems similar

no it was more recent and not as many chapters (i know it's something i commented on but it'd take a while to go through my comment history) Inio Asano is great tho

 

[EchoGirl]

(Still couldn't find it, i feel like it might have the 'psych' tag but not necessarily horror since it was a violent teacher versus some supernatural mystery aspect lol)

Edit found it lol https://mangadex.org/title/8ff21190-e159-4642-955f-d2c355c7cc58/ddaddiction
