I'm just going to bombard you with drawing and hope for the best.
The first picture here is based of a rip-off of 'Death Note'. It's from Yandere Simulators 'Life Note'.
The last three pictures you saw are drawings of Kokona, Kizana (Kokona's replacement), and Megami. They too, are also from Yandere Sim.
And this is a picture of Rin, from 'Lost Song'.
(I'm gradually running out of ideas of what to say.. So I'll end this with the next two)
Now finally, we end this off with two pictures from 'Scum's Wish'.
P.S: Since I posted pictures from Yandere Simulater, go check out Yandere Dev's channel for some reason.
