Sometime later, a large stray spirit attacked. Bell, now a friend, warned that he was responsible for making Kanon small, is the boss of the stray spirits, and he steals "dreams". The spirit then attached a line to Kozue's head making her despair and say "I'm so useless... I'll never grow tall... I have so many likes and dislikes." During Kanon's battle with him, Kanon 'speaks' to her asking if she can hear her and to be strong. This caused Kozue to snap out of her depression.
