Tensei Youjo wa Owabi Cheat de Isekai Going My Way

Synopsis:

"Once a laid-back, low-key otaku in her 30s, she suddenly wakes up in a strange forest… as a young girl! Assuming it’s a dream, she starts to explore, only to be swept into an unexpected fantasy world. Gifted with cheat-level magic, she rescues a fluffy stoat-like creature and quickly becomes part of an overprotective adventuring party. Thus begins her easygoing reincarnation adventure, blending the curiosity of a child with the overwhelming magic and knowledge from her past life!"
