Still, while Asuna thought it was feasible, it was not necessarily the best plan, because it came with several problems they would have to address.
"The best approach would be to take Roshi into Shikkotsu Forest, but I'm not sure whether the Slug Sage will agree. After all, not just anyone can go there," Asuna said.
The homes of summoning beasts belonged to them, just as everyone had their own living space. Generally, the only people who could go there were those who found their own way in or had signed a contract with them. Bringing an outsider inside was practically unheard of.
