Himouto! Umaru-chan, Eromanga-sensei Recommendations
-Both are comedies, though Eromanga has some implied romance
-Umaru and Sagiri are both similar in personality, hobbies (both are otaku) and attitude (especially when it comes to the older brother)
Both have a sister character that is a shut in
If you liked this title, you'll definitely like "Eromanga-Sensei". In both cases, the sister is an "Otaku" and stays most of the time at home, in addition, both girls have a brother.
Want to be called oni-chan? Stop dreaming, my friend.!! Watch this anime if you like the younger sister and brother genre who loves their sister..!!!
