Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei shiteshimatta..., Honzuki no Gekokujou: Shisho ni Naru Tame ni wa Shudan wo Erandeiraremasen Recommendations
Main protagonist from a josei category with a specific interests they are passionate about (books/otome games), get isekai'd into a child's body. They use their intellect and planning to get through the events in this new live like they want to (with varying results) with a clear goal in their life (read books/not trigger bad end). Both heroines tend to space out and not be entirely avare of the social situations around them.
Both are iseaki with strong female MC. Both MC have a passion for something outside of what the society they live in expects. Both are airheads when it comes to the realities of life. Finally both are amazingly heartwarming, though they both have darker moments. Otome game less so but both are quite grown up in how they present society, love, relationships, human behaviours etc. So if like me you despise fan service, unintentional groping and the like you'll enjoy these.
They both have a girl who has died and are put into another persons body. they use there knowledge of there old world to their advantage.
Are you tired of seeing isekai that feature some virgin NEET on his adventure to defeat the demon king boss guy or whatever alongside girls whose only purpose is ecchi fanservice?
Well then, I offer you these 2 anime! They are isekai, so of course they have the protagonist somehow transported into another world, but instead of following copy paste stories like the Shield Hero, Re Zero, or KonoSuba, both protagonists follow different goals as they go through their new world. Katarina's goal is to simply survive an otome game world, while Myne's goal is to read as many books as possible.
Both anime show what
a girl gets reincarnated in a different world which is somehow connected with her intrests in the past life [myne loved books so she’s in a world where she tries to create them because they’re really rare. katarina’s hobby was playing otome games so she became one of the characters]. both’s journey starts when they’re young [5 or so]
Both are similar in that both are reincarnated, retaining and using their past knowledge to help them throughout their new lives. Also, both are considered a bit odd by others and mention the past quite often to survive/navigate the new world. On the other hand Ascendance has more world building and doesn't really had romantic entanglement like this anime, where its an Otome.
-main characters transported to a world linked to their past life interests
-reincarnated at a much younger age
It has the same reincarnation genre, and uses their knowledge of the previous life to change the way things are in this world.
Both have female MC's
Both, unlike other isekai's with male protagonists, have a much more chill vibe and don't revolve around action and beating demon lords.
Both MCs are reincarnated in the body of younger girls.
Overall both animes are very wholesome, heartwarming, and interesting!
Similar cheerful MC
Both MCS were went to another world.
Similar atmosphere where both MC became important.
What this anime you wont regret it ;)
