Mikuru retreated to the upper levels of the thermosphere, ferrying Tsuruya's fang in planetsafe gloves to the moon. She was being pursued by Shamisen for some flimsily explained reason. Shamisen extended his tentacles in an attempt to slow Mikuru from reaching her destination.
"Mikuru Asahina, for your crimes against humanity, you must be annihilated and imprisoned for eternity. Prepare to die!"
"Never, you pussy!"
Mikuru fired annihilation rays from her gloves in the struggle to free herself from the cephalopodan appendages. The grotesque Shamisen let out a hellish cry of pain.
Though it took Apollo spacecraft three to four days to reach the moon, Mikuru somehow did it in 30 minutes. Mikuru hastily buried the fang at the moon. The area of the ground immediately turned a completely brown rainbow color. The moon was now safe to budge. Mikuru saw Shamisen speed toward her, so she began to make her move. But, of course, she had to make the obligatory pre-buttkicking phrase beforehand.
"In my name, the moon will punish you!"
Mikuru rammed the moon at Shamisen. Every single thing in space exploded. ISS astronauts probably soiled their diapers. The resulting collision set both the abhorrent eldritch abomination and the moon on fire, broke them up into a babillion pieces, and set all of them on fire. The conflagrant masses of Cathulhu and moonrock plummeted to the extravagant cities of Rome, Dubai, Singapore, and Boise, enveloping them and their citizens in complete hellfire. And yes, these places still burn to this day.
As Mikuru saw the spectacular display of objects that somehow burn without oxygen head off to the edges of the solar system, she just realized that she forgot one thing.
She forgot to feed Kunikida's hamster.
