"It wasn't intentional, it just happened while we were instructing her to change her shape." Lucy pointed at red head with her gaze.
"Oh, so she became bigger and stone wall couldn't hold her expansion, so it crumbled." But still something didn't match up to him, why only wall and plants at one side was damaged and nothing happened to anything on both sides.
"Yes, but....it was only tip of her finger that did it. When we stopped her from further enlarging, this side was already gone with nothing left behind."
"It was our mistake as we told her to transform her hand according to the same size as her original body."
Gin could hear her words but his gaze is at the view of wilderness outside through the not existing wall anymore, spammed over hundred meter wide.
