The story goes like this:
- Miss had a gold-badged Reimu, and as a Reimu, she wanted to have little ones.
- After denying her several times, Miss finally gave in and injected her with a Marsa paste.
- At first, Reimu was happy, but Miss cut it short by breaking the stalk and freezing the koyu, with the reason being: "Can only keep 1 right now". She promises would take care of the other when Reimu takes it easy forever.
- Of course, there is no way Reimu would accept this, but she's smart, so she waited until Miss went to work, and then she thawed the koyu by using the microwave.
- One day, koyu's skin had rashes, and Reimu tried to cure them with orange cream.
- This repeated several times until one day when she was trying to thaw the koyu, she fell. The koyu, still in the microwave, 1 exploded and 1 had a massive wound.
- Miss came home, immediately knew what happened, and explained to Reimu that the process of repeating freezing and thawing would cause a massive impact on the skin, making it deteriorate, which is why the koyu had a rash.
- Miss gave the remaining kid to Reimu. Reimu then begged/demanded Miss to save her only child left, but Miss knew it couldn't be done.
- Maricha, in a state of being heavily wounded and in madness, trying to rub rub with her mom. Of course, as Miss had said, the skin was already degenerated to the point that a slight touch could easily rip it out, and Maricha died in Reimu's braid.
- Reimu, unable to accept what has happened, caught anti-yukuritis.
