Iinazuke wa Imouto-sama!

Shun lives alone with his sister Yuna after their father remarries. Yuna acts harshly to Shun and often yells at him for the slightest mistakes. Suddenly Haruka arrives unannounced and claims to be Shun and Yuna’s new sister. Since she’s Shun’s new sister she believes that must mean they love each other and if they love each other that must mean they’re engaged to be married and if they’re engaged to be married that must mean they should do ecchi things together.

Yuna fights back for her brother and announces that she won’t give Shun up to Haruka or anyone! Haruka then concludes that Yuna must love Shun too and if she loves Shun too that must mean they’re engaged to be married as well and if they’re engaged to be married as well that must mean they should all do ecchi things together!

This game was alright, however the English patch seems more like a rough first patch then a final one. There's some parts that are still in Japanese and during Haruka's ending right before her final h-scene the text was a mess with the name of the character who was going to talk next showing up in the line of the character speaking sometimes overlapping if the line was long. I did like the artwork and I liked Yuna more than Haruka but I'm sure there are some who feel the other way. The route where you can choose both girls that unlocks after finishing the single routes was alright but it was a little irritating having to skip the entire story again to get to the choice, I would have liked to just load my save and the choice be there. I have played other titles and I'm pretty sure they worked that way. I don't think I'll play this again but it was pretty good for what it was an incest nukige.

Put all parts in one folder. Right click on first part. Choose "Extract here". When done, new folder will appear. Start the game.

I tried to download again and it still showed me this shit. Please help T.T

In every file the data02.ykc and data03.ykc fail to extract from 7zip. Basically making the game unplayable. Anyone know a fix for this? I'm also using the latest version of FireFox if that is the problem.

This is the first censored eroge I have seen, bummer would have been a lot better without blurred out erotic scenes. I hate censored anything lol

Ace03 Oct 2019Reply

I mean, I feel you bro... but in rare cases censorship is for the better.

Like this one eroge I was playing last week the dudes dick looked like a deformed reptile fetus or something I shit you not. It was fucking mortifying ;__;

Japanese artists are usually top notch but jesus christ they cannot draw dicks to save their lives lol.

Hearing tsundere imouto Yuna (played by Sakurai Harumi) calling you "Nii-san nii-san" is priceless.

Fun fact: this va plays Haruka in Beat Blades Haruka, unlike in this game.

Whoever "translated" this used MTL and didn't bother editing it. The whole thing reads like a badly written script written by a 12 year old.
