New release: “On a Summer Day, with My Kouhai, at the Bus Stop.” by Morimiyakan (Morimiya Masayuki)

A guy meets his underclassman who confessed to him a month ago at a bus stop. When he questions her feelings, she proves to him that they’re real.

Note: This story appears to have at least three sequels, but none of them have been scanned, and they aren’t sold digitally nor available on sites like Melonbooks/Toranoana so it seems pretty unlikely we’ll ever be able to work on them.

Edit (2020/10/11): The story’s sequels have been uploaded! We will try to get them done soon, people’s schedules permitting.

Release: “A Childhood Friend and Younger Sister” by Tachibana Omina

Hina can’t be with the one she loves because he’s her older brother, but she also can’t let go of him. Her friend Hana, who is into the occult, lends her a mysterious crystal that can supposedly let someone switch places with another person for one day. Turns out the crystal’s powers are for real, and Hina ends up switching with Yui, her brother’s girlfriend.

A bodyswap between girls feels rather rare, and the threesome action was hot. I hope you enjoy it!

As the title suggests, an otaku crosses paths with a gyaru. All I’ve got to say is Kirari is freaking hot.

And yes, it does seem that the artist intentionally had Kirari call the protagonist by the wrong personal name. Twice. I’m not sure why he didn’t correct her.

Chapter 1

Even though Shinya agreed to stop having sex with Yuina, he secretly continues to do so. Troubled by this secret, he confides in Yuina to figure out what to do, and she comes up with an outrageous solution that just might work.

Sorry that it took so long to release the final chapter. There’s no good excuse for it; I just couldn’t muster the motivation to edit it until now (I finished the translation long ago).

Release: “Boyish Girl Friend” by SHIS (Z-ton)

Warning: This story contains some sex that is arguably forced and not entirely consensual. For this reason, I wasn’t completely sure if it should’ve been a Team Koinaka release; it’s a borderline case. If you feel you will be bothered by that, then perhaps you may wish to skip this release. Thanks for your attention.

Satsuki frequently drops by the reading room of Kusuki–a childhood friend–to kill time after school. One day, she discovers some of his porn magazines, and is surprised to find that it’s about girls like her. I did not steal this description from “Abs-solutely Close-Range Love”, no sir.

I’ve long liked Z-ton’s slender girls, and it was cool to see them do something a bit more “normal” this time i.e. non-monster girls.

Release: “The Siblings’ Secret Nest” by Aoki Kanji

Koyuki and her older brother are in love with each other, but know that entering a relationship would bring hardship to their lives. Nevertheless, they work toward a future where they can be together.

Unlike Aoki Kanji’s other brother-sister incest works, this one stands out as taking the subject matter more seriously. Nevertheless, I hope you enjoy it! (If anyone is able to acquire better raws for Aoki Kanji’s COMIC Grape Vol.50 story, please let us know. I’d love to work on it, but I think we’ll have to pass on such low quality.)

Release: “Leave Me Alone!” by Abe Morioka

Sakae is indifferent about her future and school attendance, but her childhood friend-turned-teacher Hei adamantly tries to help her graduate and be on the right path. She comes up with a plan to get him to stop pestering her.

This is honestly one of the best stories I’ve read, and it hits all the right notes for me:
☑ Childhood friend
☑ Oral/69
☑ Defloration
☑ Anal
☑ Light femdom-ish elements
☑ Thick eyebrows
☑ Funny
☑ Romantic

The only reasons I didn’t work on it sooner was because I holding out for a tankoubon release (the censorship is unfortunately pretty bad), and the editing was nightmarish. I finally grew tired of waiting, so here you go. Hope you enjoy it!

Release: “Sweetitivity” by lunch

Sae is popular and loves sweets. She receives a lot of chocolates on Valentine’s Day. Her boyfriend Mutsuki is just the opposite; he doesn’t get any. Sae senses his unhappiness and decides to give him a present to lift his spirits on their way home.

I’m honored to present this story, the last known work by lunch that hadn’t been translated into English yet. It has some special significance to us because our group is named after lunch’s one and only tankoubon, Koinaka. It’s still sad that lunch completely vanished from drawing manga, adult or otherwise, after 2012.
