Memories of Mother – Onee-chan is in Trouble - S1.E20

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