This curious User probably isn't a physical threat, but Yori's careful to answer with courtesy. "Yes, sir. I don't know whether these plants are dangerous or not." Many plants are, especially to Users who rely on such a strange network of chemical reactions to survive.

Yori hasn't heard much warning about this island, since the one that's falling apart is the more obvious threat. However, she wasn't planning to stay more than a moment.

It's strange how even a moment makes her worry even more than usual about all the risks involved here.

"Some small chance to grow here instead of drowning is all I can give them. I haven't studied anything about plants." She could have learned a little back on the station, but avoiding an enemy took priority.
