Hitori Camp shitara Isekai ni Teni shita Hanashi

Kaede, an office worker, is on a solo camping trip in the mountains to heal from a broken heart, when she finds herself in another world. At first, she lives a life of life and death, intimidated by the strange monsters she has never seen before, but with the attitude that it can't get worse, she perseveres. She also becomes friends with Fenrir and fairies and gets adapted to this other world, but... So begins the isekai camping life of Kaede, a woman with amazing initiative!
