PLEASE WATCH IT ON YT IS FREE https://www.youtube.com/watch?v=j3hyRR3_q1E also engi i trust u to give much love to inori and tsukasa sensei cuz not then 2025 will be the end of me
i didnt remember the ml and fl names but ml wears glasses and has black attire while fl is into lolita fashion with twintails.
also important fl has a knack of falling for red flags (like serial killers, stalkers,etc) and ml have to beat all of them, being her personal body guard (?) to find out about his sister's death.
there's one scene i vividly recall is the fl's brother swallow a whole bunch keys and trap them inside a room with him.
hope the description clear enough.
like i think they have the same team who work with alien stage (my hyperfixation) so im guessing
