Isekai Shoukan ni Makikomareta Obaachan: Mori de Nonbiri Sasete Itadakimasu (Associated Names)

I got involved in a different world summoning of high school students, but since I’m unrelated, I shut myself in the forest. I planned to live my remaining years leisurely, but I seem to be able to use magic for some reason, so I think I will try little harder to live.
