Was waiting for this to be translated. The artist really knows how to do monster girls

This is probably the weakest of these stories, art-wise. It's not bad, it's just... rushed, I guess?

Frog girl is still the best one.

>>Patterned
That's true, there are hardly any background at all in 32 pages, and the shading seems a bit hasty.
Nevertheless, it's still awesome.

...monster girl, plus a sweet story with a sappy ending.

I love you Jingai Shunman 4, I love you.

'IGHT!, translating dialect is always interesting.

Base +8, crazy4sian +8

Let us all celebrate how beautiful this story was for a moment.. MOMENT OVER! This was good, but like everyone said, Frog Girl is the best one. Personally I prefer the Ant One for its ending, but to each his own.

Base +5

Shadow Over Innsmouth? Those Deep Ones aren't going to make themselves guys!

I loved this story, cute girl and some romance.

Base +7, danixxx +30, Mr.Hero +1, jaylou1010 +7, Amakawa_Yuuto +14, crazy4sian +8

Too bad, I wanted to see the kids.

Base +8, Mr.Hero +1, crazy4sian +8, sockpuppet56 +4

One of the best monster girl story lines I have ever seen. Other than the censoring and lack of backgrounds it was perfect.

Thank you rabbit for the wonderful translation. Sure it takes a while, but it's all more than worth the wait if we keep getting gold like this.

Base +5

I love how hot Toumasu's comics art, and how adorable the girls are, but at the same time, he always fits in enough romance so that it's not just mindless sex.

Base +6, MilkTeaEgg +6, SciFiMisc +6

:/ I kinda wish she was more mermaid. You know, as in mermaid tail. But legs... with flippers for feet? That's just kinda are weird, imo.

Base +11, Amakawa_Yuuto -14, ShadowSynergy -6, Redstar1357 -5, SciFiMisc -6, Kastev -13

I fucking love these ones. Thanks a bunch!!!

Base +6

He is one lucky freaky fish guy.

Base +8, tobeunforgiven2 +13, CyborgSamurai +6

I don't even e-hentai

Base +1

Thank you Niku Drill for opening a whole new world to me, and props to the translator as well.

Base +6

a girl full of eggs.... I like it....

Base +9

A boy and his Deep One. Interesting detail on the eyes. She's never without sight, not even for a splitsecond.

Base +2

@Lawcol1
Fish don't have eyelids, so my guess is the artist gave her transparent ones, sorta like some frogs also have transparent skin, and to still keep that ratio of monster to human the artist is known for.

Base +5

A man and his beloved undine.
