tsui no sora is what happens when you try to make hentai in mario paint. i swear, this hentai is funnier than 90% os comedy anime solely due to how horrendous the animation, line delivery and screenplay are. i genuinely think this is the first time i couldn't stop laughing while watching anime. i dont know how to write reviews, so if this is unorganized as fuck, im sorry. the plot is fairly simple. girl gets fucked by 40 year old highschool kid then commits suicide, then 40 year old hs kid kidnaps girls and takes them to his sex dungeon (?) to prevent the end ofthe world, which isn't actually real and it was just a lie? idk it gets super weird towards the end.

the animation as previously mentioned, was most likely made in paint, with a mouse. the characters go really off model sometimes, the proportions are fucked up, i remember one time the main character's mouth just disappeared halfway through his line.

so why did i give it a 10? simple. i have never been this amused by a hentai in a long time.
