Four koyukkuri are enough!
Panel 1: I gave Reimu and Marisa a stern lecture.
[Narrator] What will happen to this other little one if you refresh now? He might not be born easy!
They promised to be good for the unborn little one's sake.
Panel 2: Just in case, I make Marissa hunt-hunt for food everyday.
Panel 3: After playing with the koyukkuri and hunt-hunt all day, Marisa is too tired to refresh.
