When Bu-Ling falls sick, Ichigo, Minto, and Retasu agree to go to pick up Bu-Ling's little sister Heicha from school. Heicha's teacher explains that Bu-Ling's mother died and her father is always traveling, so Bu-Ling is the primary caretaker of her five siblings. The little girl refuses to leave the school with the others, but Bu-Ling arrives to get her. The others go with them back home to help care for Bu-Ling's siblings. The next day, Heicha's teacher drives her home and offers to help Bu-Ling, but Bu-Ling declines her offer. Tart appears and steals the teacher's spirit to make a chimera anima. Bu-Ling is still too sick to fight, but the others arrive and defeat it. Later, the teacher offers to drive Heicha to school, but Bu-Ling says she would not get to see the teacher anymore like that. Instead, she asks the teacher if she can pretend to be her mom for a little while.
