最高の漫画（ぜひアニメ第二期を!）

The best manga (be sure to watch the second season of the anime!)

ねことうふさん、とても面白い漫画をありがとうございます。私もこの世界に入ってみたいと思いました。私的にはぜひ地上波（フラアニとか）で第一期の再放送と第二期を放送してほしいです。私の推しはみはりちゃんとまひろちゃんです。物語がとても面白く、絵もかわいいので十一巻（最新作）まで買いました。ぜひ続きとアニメ化の検討よろしくお願いします。続きが読みたいです!

Thank you, Cat and Ufu, for this very interesting comic. I wanted to enter this world too. Personally, I definitely want them to broadcast the first season reruns and the second season on terrestrial broadcasts (like Flaani). My recommendations are Mihari and Mahiro. The story was so interesting and the pictures were cute, so I bought up to 11 volumes (latest work). Please continue and consider animating it. I want to read more!

ほのぼの女体化

Heartwarming feminization

アダルト系の女体化ではなく健全ほのぼの女体化ジャンルがよくできてて面白い！否定しながら徐々に心も女子に、このまま親が戻ってきても男に戻らず継続して欲しい

It's interesting that the healthy and heartwarming feminization genre, not adult feminization, is well-made! While denying it, I want my heart to gradually become a girl, and even if my parents come back like this, I want them to continue without going back to being a man

お馬鹿で面白い

Stupid and funny

題名と紹介に期待していませんでしたが、読んでみると、お馬鹿なほのぼのコメディーそのものの、少しエッチ味つけの作品で、その内容に絵もぴったりあっていて、とにかく面白く感じました。

I wasn't expecting the title and introduction, but when I read it, it was a silly, heartwarming comedy, but it was a slightly naughty work, and the pictures fit the content perfectly, and I felt that it was just interesting.

あらまー

Oh my gosh

とてつもない設定なのですが、そこさえ受け入れて仕舞えば可愛くて楽しめました。絵柄も可愛い。性別が変わるだけで許せることってあるなぁと思うと男性は大変だなと思います

It's a tremendous setting, but once I accepted it and finished it, it was cute and I enjoyed it. The design is cute too. I think it's hard for men to think that there are things they can forgive just by changing their gender

Sweet　満腹だ

Sweet I'm full

読み始めた頃は少し共感性羞恥心を煽られる感じかなと思ったんだけど、今となってはそれもスパイス。ひたすらに登場人物が可愛らしく愛らしく、堪らない。単行本に載ってるおまけや○○.5話はこの作品を深めてくれる触媒。ありがとう。ただそれだけでいい。

When I started reading it, I thought it was a little bit fueled by empathy and shame, but now that is also spice. The characters are just so cute, adorable, and unbearable. The bonus episode ○○.5 in the book is a catalyst that deepens this work. thank you. That's all it takes.

個人的な感想だけど自分的にはすごく面白いしｔｓ感がたまらんのでまだまだ続けて20巻ぐらいまではいってほしい

It's a personal impression, but it's really interesting for me and the TS feeling is irresistible, so I want it to continue and get to about 20 volumes

アニメとはちょっと違った

It was a little different from anime

初めにアニメを見ていたからか、少し違和感が多かったけどふつーに面白かったです趣味と書いてエロゲと読むのか。勉強になったほかの人にもおすすめできる

Probably because I was watching anime at the beginning, there was a bit of a sense of incongruity, but it was usually interesting. Do you write it as a hobby and read it as erotic. Can I recommend it to other people who have learned

神。

アニメ見て、まだアニメ化されてないところが気になって買いましたけど、普通に神ってます。マジで。作者は天才。崇拝します。この漫画を読んで俺は何かに目覚めました。とにかくね。この漫画のおかげで自分変われました。いつか俺が亡くなったら、俺の墓にこの本を置いてください。

I watched the anime and bought it because I was curious that it hadn't been made into an anime yet, but I'm usually amazed. seriously. The author is a genius. I adore you. Reading this comic made me wake up to something. anyway. Thanks to this comic, I was able to change myself. If one day I pass away, please put this book on my grave.

アニメも最高

Anime is also the best

なんだろう、面白いんだよね。なぜか見ちゃう。少しずつ色々成長していく姿も面白い。ゆっくりまったり、心が優しくなれる。

I wonder what it is, it's interesting. I'll watch for some reason. The sight of them growing little by little in various ways is also interesting. You can relax and be kind to your heart.

ある意味生まれ変わり

Reincarnation in a sense

女体化と言うものはある種の転生に近いと感じた。女体化前の主人公を自分と重ねてしまう自分が居て少し複雑だが、面白い。

I felt that feminization was close to a kind of reincarnation. It's a bit complicated, but it's interesting because I have a self where the main character from before feminization is superimposed on me.

久しぶりに面白い漫画が読めました

I haven't been able to read an interesting comic in a long time

私は、読みたい漫画に偏りがあるので、あんまり合わない漫画が多いんですが、こういう日常系の漫画は読みやすくて好きなので、こういう漫画があれば積極的に読んでいきたいなと感じました。日常系の漫画にねじ込まれている嘘も「お兄ちゃんが少女化した」という一つだけなのでとても分かりやすいテーマの漫画になっています。

I'm biased about the comics I want to read, so there are many comics that don't really fit, but since everyday comics like this are easy to read and I like them, I felt that if there were comics like this, I would like to actively read them. The lie screwed into everyday comics is also a comic with a theme that is very easy to understand because there is only one thing called “My older brother turned into a girl.”

よきよき

Good good

TS漫画が嫌いな自分でも楽しめました。というよりまひろ(主人公)が可愛いので男の子ということを忘れてしまいます(笑)もちろん他のキャラも可愛いです。特に妹のみはりがめちゃくちゃ可愛い

Even if I don't like TS comics, I was able to enjoy it. Or rather, Mahiro (the main character) is cute, so I forget that he's a boy (laughs) Of course the other characters are cute too. My little sister Mihari in particular is insanely cute
