My Friend’s Little Sister Has It In for Me! Season 2 Release Date

When My Friend’s Little Sister Has It In for Me! (Known in Japanese as: Tomodachi no Imôto ga Ore ni Dake Uzai) is wrapping up its first season, a lot of viewers realized something unexpected had happened. What looked like another loud teasing romcom slowly turned into a character driven story with real emotions underneath. That shift is exactly why so many people are now waiting for news about Season 2.

A Quick Look Back at Season 1 So Far

Season 1 centers on Akiteru Oboshi, a high school student who values efficiency, logic, and building a future over romance. He’s part of a small indie game development group and wants to turn it into something serious. Dating, flirting, and youth drama just feel like distractions to him.

That calm approach collapses when Iroha, his best friend’s little sister, starts invading his personal space and teasing him nonstop. Her behavior is loud, confident, and often crosses the line, but it’s never random. Alongside her is Mashiro, Akiteru’s cousin, who enters his life through a fake boyfriend arrangement that quickly becomes emotionally real for her. As the season goes on, it becomes clear that none of these characters are playing games for fun. They’re all struggling with feelings they don’t know how to express properly. If you haven’t seen it yet, check out the official trailer for Season 1 down below to get a feel for the energy and character dynamics.

The last episode of Season 1 is set to release on:

1. Episode 12 (Finale) - December 20, 2025

That episode is expected to close the main emotional arc while leaving just enough unresolved tension to make a continuation feel necessary rather than optional.

Season 2 Release Speculation and Timing

There is no official confirmation for Season 2 yet, and that’s important to say upfront. However, looking at the situation realistically, a second season is far from unlikely.

The anime adaptation was first announced years before it actually aired, which suggests the production committee has been cautious and long term focused. The source material still has plenty of content left, and audience engagement has remained steady throughout the season rather than dropping off. If a renewal announcement happens sometime in 2026, a release window in late 2026 or early 2027 would fit normal production timelines for a series like this.

What Season 2 Would Likely Focus On

If the anime continues adapting the light novel and manga, Season 2 would shift away from surface level teasing and move deeper into emotional consequences. Based on where Season 1 leaves off, likely developments include:

1. Iroha confronting how her teasing has started to hurt both her work and her confidence
2. Mashiro becoming more involved with Akiteru’s game development group and revealing more about her past
3. Akiteru finally questioning whether avoiding romance is actually helping or holding him back
4. Growing tension between ambition and emotional responsibility
5. Otoi stepping into a more central role as emotional support rather than background commentary
6. The teacher Kageishi becoming more relevant beyond comic relief

Season 2 would probably feel more mature, slower paced, and more focused on internal conflict than Season 1.

Why Opinions Changed After the First Few Episodes

Early reactions to the anime were mixed. Some people found Iroha annoying. Others felt the teasing was too aggressive. A lot of viewers compared it to similar shows where the dynamic never evolves.

That perception changed later. Episodes like episode 9 made it clear that the characters were not stuck in place. Iroha’s jealousy starts affecting her voice acting work, and she clearly hates what she’s becoming. Mashiro’s confession and refusal to quietly step aside showed emotional strength instead of cliché resignation. Akiteru himself stopped feeling like a generic dense protagonist and started looking more like someone actively suppressing feelings for practical reasons.

Those shifts are why Season 2 now feels necessary rather than optional.

What Viewers Want from Season 2

Most people aren’t asking for bigger jokes or louder moments. They want progress. Real decisions. Consequences.

There’s a strong desire to see Akiteru stop hiding behind logic and face the emotional impact he’s having on the people around him. Viewers also want Iroha to grow beyond teasing and prove she can communicate honestly. Mashiro’s future is another major question, especially since she’s shown she’s willing to wait but not disappear. As Tomori Kusunoki put it when talking about playing Mashiro,

“I am excited to show her full salty side in animation. I am ready” - Tomori Kusunoki, VA of Mashiro

Interestingly, many viewers are also curious about the teacher Kageishi. What started as a joke character now feels like someone with narrative potential. That kind of interest usually only appears when a series has successfully built trust with its audience.

The Author’s Style Explains the Shift

One reason this anime surprised people is because it comes from the same author as Days With My Stepsister. That series was quiet, grounded, and emotionally restrained. This one starts loud and chaotic, then slowly peels back layers.

That contrast makes more sense once you realize the author doesn’t stick to one genre or tone. The teasing isn’t the point. It’s the shield. As the author explains,

“No matter how good a plot you have, if the characters are not lovable as human beings, it will not feel like a good story” - Ghost Mikawa, original author

Once that drops, the story becomes something closer to a drama than a pure comedy. Season 2 would likely lean further into that identity.

Why Season 2 Feels Earned

Not every romcom deserves a continuation. This one might. By the end of Season 1, the characters are no longer static. They’ve been hurt, confused, and forced to reflect. The game development plot has grown into more than a gimmick, and the romantic tension now has emotional weight behind it.

All episodes of Season 1 are available on Crunchyroll for those catching up. And for readers who enjoy speculation, check out our previous articles on Sanda Season 2 and Tales of Wedding Rings Season 3 ,which explore similar renewal situations.

If Season 2 happens, it won’t just exist because fans want more. It’ll exist because the story isn’t finished saying what it set out to say.
