Kousaka Kirino is a model who excels in everything and whose best friend absolutely hates otaku. However, Kirino has been hiding a secret; she’s an otaku who loves imouto related eroge and magical girl anime. She hasn’t told anyone, and doesn’t even talk to her brother Kyousuke, but one day, Kyousuke finds out Kirino’s secret. Kirino decides to force Kyousuke to engage in her otaku hobbies with her and help her in the world of all things otaku related.

When you’re talking about imouto anime, one of the top anime that comes to mind is OreImo. This anime has two seasons featuring Kyousuke and Kirino and their rather complicated romance that tends to get otaku talking. If you want otaku themes, complicated relationships, a bit of a harem like Ore ga Suki nano wa Imouto dakedo Imouto ja Nai!, and a bit of comedy, keep an eye out for OreImo!

Izumi step siblings Masamune and Sagiri have been living together for a year, but Sagiri shut herself in her room after the death of their parents. Masamune worries over his new sister so he takes the time to bring her her meals and try to talk to her. Meanwhile, Masamune helps to make ends meet by working as an erotic light novelist. He works with the talented Eromanga-sensei, who turns out to be Sagiri!

Eromanga-sensei came to us in 2017, which celebrated quite a few imouto anime. Similar to Ore ga Suki nano wa Imouto dakedo Imouto ja Nai, we get an anime about light novelists, an imouto who has a bro con but refuses to admit it, and a fun harem of girls who somehow get involved. While the romance doesn’t escalate quite like OreImo, and the siblings are step siblings, it’s still an imouto anime that might just catch your eye!

Hashima Itsuki is a light novel author who loves all things little sister, even though he doesn’t have one. While he may be a bit imouto obsessed, he still has good friends in Nayuta, Haruto, and Miyako. Meanwhile, his step-brother Chihiro comes along once in a while to take care of the housework and cooking for Itsuki. Every day is full of fun while also fitting in time to write light novels.

Now, Imouto sae Ireba Ii. is not your run of the mill imouto anime because there’s technically no outright imouto like the others. Instead, you have a light novelist, Itsuki, who is a siscon with no sis! Still, that doesn’t take away from the great harem, drama, and complicated feels each character has. Plus, there’s a lot of slice of life fun as we dive into the world of light novelists in Imouto sae Ireba Ii.

After being apart for 6 years, siblings Akiko and Akito will finally live together. Akito is determined to provide for both him and his sister, while Akiko is making up for their 6 years apart by being a doting and affectionate little sister. Unfortunately, Akiko may have some competition as their other housemates also have their eyes on Akito!

If you wanted a deeper look into bro complexes, Oniichan dakedo Ai sae Areba Kankeinai yo ne! will have you covered. Follow Akiko as she obsessively dotes on her big brother who appears to be perfect in every way. Then we have the harem of girls who also like him, but who can lose to a little sister? If you just want the obvious brother complex of Ore ga Suki nano wa Imouto dakedo Imouto ja Nai and don’t mind a lack of otaku references, OniAi may be for you.

Alice of Alice: Siscon Niisan to Futago no Imouto follows the Alice twins and their love for their older brother, who loves them back all the same. There are other girls involved, but it’s all about Airi, Rise, and their beloved older brother!

This is a short anime that’s mostly just for ecchi scenes and brief injections of sis-bro con in your life. Watch the Alice twins as they dote on their brother or enjoy watching the older brother take care of all of Airi and Rise’s needs. If you want an unhealthy sibling relationship taken to a whole new level, you may want to check out Alice or Alice: Siscon Niisan to Futago no Imouto. Did we also mention that it’s extremely ecchi?

Doma Umaru is perfect in everyway at school, but at home, she’s the lazy otaku who dresses in a hamster hoodie and only worries about her hobbies. Meanwhile, Umaru leaves all of the household chores and tasks to her older brother, Taihei. Taihei is determined to get Umaru to be a proper young lady, but we’ll see who will be on top!

Stepping away from the incestuous relationships, we take a look at Himouto! Umaru-chan where we have a sis and bro con that is milder than the rest. Umaru clearly cares for her brother and may sometimes have a hard time sharing him, while Taihei’s life seems to revolve around Umaru and caring for her, even if that’s not necessarily a choice. Still, you get to enjoy a lot of otaku references in Himouto! Umaru-chan, more so than Ore ga Suki nano wa Imouto dakedo Imouto ja Nai which only seems set in that realm. This one is based more on comedy and slice of life, but it’s still a good anime to catch!
