Otome Anime Quick Transmigration Novels

What if you quick-transmigrated to an anime multiverse and embarked on a series of romances and adventures with characters from all kinds of anime? Character introductions: (Main character from the supernatural anime: Keke, female, 152 cm tall. She has brown hair in twin buns, wears a headscarf, a white T-shirt, and a shoulder bag, and has a sweet appearance. Her body can instantly transform into that of a shrine maiden, allowing her to brew all kinds of potions and conduct experiments. She also has offensive supernatural abilities. She's scatterbrained and a little lazy. Her unusual powers are rare and immensely strong, allowing her to quietly defend against any powerful supernatural attack. She's known as a "national treasure esper.") (Other supporting characters: no introductions) (Male leads: Kakashi, Shinnosuke Nohara, Hanako-kun, Houtarou Oreki, Chuuya Nakahara, Osamu Dazai, Nikolai Gogol, Fyodor Dostoevsky, Victor Hugo, Huarong, Squidward, and others.) (Characters such as Keke, Baoli, and Buji are borrowed from other novels.) Theme: With the protagonist's halo at her side, she faces everything bravely and without fear. Told in first person. Let the story begin! [Absurd comedy + quick transmigration + sweet slice-of-life + lots of crossover with Bungou Stray Dogs + unexpected character contrasts] Note: If it's not to your taste, please don't leave hate. Thank you!
