I will never forgive the Japanese for what they did to this manga! Meanwhile another generic isekai get another anime, screw them and their shit taste!!
It didn't deserve to go out like this man...
I'd say hiking because it's the most secluded option of the 3 so low chance of distractions, also we might encounter a shrine which could give us some clue of what's going on.
And there you have it, Tomoko finally admits she isn't a loner anymore.
I'm so proud of her.
2021 is going to be the year this manga probably ends and I dread it :(
