Okay folks lets me summarize this show quickly. (It's the adaptation of "Non Human life" hentai manga chapter 1 by the Artist Kimura Neito) Contain Spoilers Plot and characters 7/10: it's just your typical lovey dovey story about our mc and his childhood friend & future lover succubus.another character is an elf teacher who can grant wish by giving her a semen.long story short and a twist our 3 main character have group sex in the end when the sensei elf grow a dick(futanari) and they double penetrate the cute succubus.

there's a little high and low moment of the story like jealousy and winning back trust but yeah it has anime classic cliches.

Animation & sound :7.5

Its exactly your average 2d drawn from earlier 2010 animation
and hey It's very rare to see 2d animated Japanese uncensored this 2018.
Overall enjoyable if you love Futa,Succubus,double penetration and happy sex.
