Itsuki Hashima is a light novelist obsessed with little sisters, strictly focusing on them when he writes his stories. Despite his personality, he is surrounded by a tight circle of friends: Nayuta Kani, a genius yet perverted novelist who is in love with him; Haruto Fuwa, a fellow male author whose work has seen considerable success; Miyako Shirakawa, a good friend that he met in college; and Chihiro, his perfect younger step-brother who takes care of the housework and cooking. Together, they play strange games, go on spontaneous journeys, crack silly jokes, and celebrate each other's successes. However, each individual must also deal with their own issues, whether it is struggling to meet a deadline or coming to terms with traumatic events buried in their past.

I love how obvious it is that the people who left all of these other reactions haven’t even seen the first episode.


Season 2 of Eromanga Sensei. This time they added a trap to the harem.


If Eromanga Sensei and Oreimo had a baby, they really should have had an abortion…


Well written characters and nice overall mood, would love to watch more of their story!


Tamer than what the title implies, but I don’t want a normal person to know I watched it.


Starts out stupid af. But it ends up as an anime I love with all my heart. All characters (Nayu) are fantastic, and the humor is on point.


This show is way smarter than it has any business being. Don’t judge it after the first 3 minutes of the show — the rest of it is different
