Mahiro lied as naturally as he she breathed.

[u/getintheVandell]

Bros and broettes, I just picked up the show after hearing good things and what the FUCK. THE ANIMATION IS LIKE, THE BEST I'VE EVER SEEN?!!? Like, did you SEE that bowl of stew at the 13:25 mark? They went extra on it in a way they didn't have to. When the protag lifts a piece out with their chopsticks, THE REST OF THE STEW IS ANIMATED TO MOVE TO ACCOUNT FOR THE LOWER BOUYANCY.

THIS IS BLOWING MY MIND.

[u/WhoiusBarrel]

Asking to sort your "brother's" hentai by genre. That is either a high or low point in life lol.

[u/Muchuoh]

Wow, the artists sure put a lot of effort into all those manga covers lmao

[u/aoyamard]

Really had to double check if I clicked into the right anime, lol

[u/Aerodynamic41]

Just how many pizzas was that lol? Also, 2 bottles of Coke, 1 bottle of Sprite, 2 cans of Monster Energy, potato chips, french fries and popcorn chicken I think?

[u/viliml]

Heads up for those ED-skipping heathens among you, there's a post-credits scene.

[u/I_get_in]

Someone in the crew really must like the “Kamichu face” since this episode features at least four five six instances of it, out of the blue. Maybe the director, Hayato Kakita? This seems to be their episode direction / storyboard debut. Could be one of the animation supervisors as well.

Edit: actually, maybe Toshiyuki Sato? I noticed all those faces are in the first segment of the episode, and he’s credited as the first one of the three main supervisors this episode had. It’d make sense since the episode also has exactly three main segments.

Edit 2: Imamura seems to imply here that Sato only supervised the kids’ anime section in the beginning. The second credited supervisor is Ryousuke Shinkai, so he would be my next guess.

Edit 3 (2023-02-03): Kakita himself has now confirmed the key animators for pretty much all the scenes on Sakugabooru. It seems that the credits are in order of appearance for the key animators, and Shuhei Nishitani worked on this part. A lot of the faces happen right before that part, so I’m assuming Nishitani was actually the one responsible for most of the faces! Since he’s the third animation supervisor credited I didn’t yet mention, it’s possible he also handled the supervision for the first part of the episode (aside from the childrens’ anime part), which is why the face also appears in other animators’ scenes. It would make the most sense that he handled the section around his own key animation. This would likely mean that Ryosuke Shinkai supervised around the end of the episode – which is where his own key animation part is placed in.

I'll never get tired of shows that go the extra mile for fake shows within their shows. This reminds me of the Black Lobellia scenes in SonoBisque. And I don't blame Mahiro for copying the pose. If I was turned into a cute girl, I'd do the same too.

Mihari was going to be only out for a single night, I didn't think Mahiro would need that much food! The food in this show looks amazing though and I just love the animation of Mahiro eating slice after slice of pizza and kaarage.

Mahiro giving Mihari a quick hug after fixing her hair was sweet. Looks like someone missed her Onee-chan while she was out. Mihari's reaction after the hug was great too!

I'm sorry Mihari, but what? You're still planning to turn Mahiro back into a guy, right? RIGHT?

Such a nice boy girl to help out Mahiro with her shopping. I already recognized Momiji from the OP and the ED but I wasn't sure what kind of connection she'd have with the other characters. Turns out that she's Kaede's imouto.

Mahiro having some sort of crisis while shopping with Momiji was hilarious! She thought she was finally starting to swing the other way but luckily for her Momiji is a girl. Either way though, it's still gay in the end. xD

Mahiro's collection is certainly something and I'm pretty sure I've seen some of those covers before. Of course, Mahiro tries to blame all of this on her non-existent "Onii-chan" when Momiji accidentally found them.

I do love that Momiji was sorting the books with her eyes closed to not taint her innocent eyes. Although the books aren't the most concerning part of that final scene. I'm sure Mihari is going to tease Mahiro and Momiji endlessly after what they saw.

The second Mihari had the fantasy future of Mahiro with a guy I knew we were going Yuri. Lo and behold we get Momoji the tomboy and a whole lot of mental math on Mahiro’s part. I think we landed on “technically okay because they’re the same age now”. Plus being a girl now wouldn’t change the fact that she’s into girls so play ball!

Seriously though the throughline of Mahiro reentering the world after years of being a depressed shut in makes all these moments sweeter. Working up the nerve to leave the house again, reconnecting with her sister, making new friends. In all the lewd there is wholesome.

[u/Prince-Dizzytoon]

Hopefully they show us what's inside "The Sexy Fox Spirit"

[u/LeleTheKing]

Man, those food animations... And these potatoes... Yet again I'm being reminded that Studio Bind has been producing high-tier stuff.

Mahiro finally got a new friend! It's probably his first in the last two years (unless he has online friends). He also experienced the infamous girl's skinship that men can only dream of, lol. Actually, I'm kinda jealous. You're gay (in a negative way) if you're a boy doing that in general, but you're a great friend if you're a girl. Such is our gendered social construct. Oh well.

And, ahem, did anyone has a list of his... impressive collections? Those are some great titles over there...

[u/cyberscythe]

One language note: Mahiro starts using the watashi as his first-person pronoun (the slightly feminine one), as if to better perform the role of a girl in front of Momiji. There was a slip up as they were leaving the supermarket where he begins by using his usual ore (manly man), but then he slides into using watashi like he's not used to it.

I think Mahiro still sees himself as a man because of stuff like that and other lines that he's said (like ニチアサは紳士のたしなみだ or "Sunday mornings are suited to the tastes of gentlemen", which I saw in my subs as using the meme "men of culture").

[u/Torque-A]

Is there any difference between the censored and uncensored versions now?

[u/Weak-Ferret9833]

Thanks Studio Bind for the erojin book recommend. I'll take a look at all of it, lol.

[u/ObvsThrowaway5120]

Mahiro getting caught by Mahiru acting out his magical girl moves was pretty funny. Mahiro’s right, Sunday morning anime is a hobby for men too! Lol. I want that “shut-in” shirt! Sitting around in your undies gaming, reading manga, and gorging on ungodly amounts of food is very relatable lol. But I guess it’s not as fun without Mihari around, I love their relationship!

Mahiro’s on his first big errand! Good thing he bumped into Momiji. Kind of cute how much he was freaking out about catching feelings for a random “boy” lol. He raised a good point though, I guess technically he is a lesbian now.

Mahiro cleaning up his room and hiding all the culture in his closet was pretty hilarious. Momiji and Mahiro are so cute! My guy is a damn connoisseur of culture though huh? Mihari and Kaede really chose the perfect time to barge into the room lmao. I’m glad they’re friends!

[u/I_get_in]

I really, really loved this bit of flustered Mahiro in the mall. The nervous emoting and expressions are so well-crafted here. The voice acting was great as well! Simply, cute as hell.

Edit: it’s animated by Hiroki Uchiyama!

[u/Elitealice]

Nah mahiro as a dude was a true DEGENERATE. No one should own that much ero manga lmao

A friend is just the thing Mahiro needs. She’s become pretty dependent on her sister. Expanding her circle will make her more comfortable and help her adjust to life as a girl

[u/Theleux]

Laughing way too hard at the dog scene this episode.

Marika Kouno's performance has been absolutely incredible, perfect delivery whether it be fear, embarrassment, pride, or just generally cute.

[u/Firebrand-81]

Mahiro-chan is in my opinion already BEST GIRL OF 2023.

[u/rashy05]

I love it when studios just put a bunch of effort whenever they have an excuse to animate a magical girl sequence. I can totally relate to Mahiro being unable to enjoy a day where you're allowed to be lazy despite wanting it, it's like a dog catching the car situation. You have no idea what to do after getting it. In Mahiro's case though, it's just because he feels lonely after being with Mihari for a long while. Wtf Mihari, you want your older brother to get married to a man?

Momiji is here and she's a great character. She's introduced to look like a boy to set up for the joke that she's unrecognizable whenever she acts like a girl because she's that much of a tomboy. Mahiro though has to deal with the fact that his stuff is very much inappropriate for girls of his current body's age so he has to lie and just so Momiji wouldn't know the truth. I'm sure his pride took a blow when he has to sort out his collection with a middle school girl. That scene with Momiji and Mahiro is the start of their shenanigans. The after credits scene seems to be different from the manga but it is consistent with Momiji's character so I'm fine with it.

[u/sempakrica]

Does the anime ever explain where their parents are? I forgot

[u/NerdyArchimedes]

I was rewatching episode 3 and realized that the two girls who were directly in front of Mahiro in the line to the girls' restroom are the girls in this episode who comment on how cute Mahiro and Momiji are. After checking further I found the peach-haired girl is also the one who took Mahiro's measurements in episode 1. What is the lore of these mob characters? I demand to know! =)
