I played Ar nosurge DLC "Nei, Far Away" again. I guess every game player who had read the novel did it. By playing over now, I was impressed that Yumekichi's 3-D figure was very elaborate either. It is slightly scary when his mouth moves; I think it superbly expresses Nei's sense.
Nei Yuuki:
Ah, well, his name is Yumekichi!
He is a robot with A.I. I just have finished last night.
