Only I Know the World Is Ending and Getting Killed by Rampaging Beasts Only Makes Me Stronger - c1-c31 - 18+ tag is only for gore stuff and it definitely fits. Blood is depicted in hectoliters.

Aria of the Beech Forest - volume 1 and half of volume 2 - cute enough to keep my suspension of disbelief about a girl living alone in the forest not knowing what technology is and hear reaction to that technology.

she is beautiful just got into 4 chapters so far but the title of second chapter couldn’t be more poetic.
