It's the nineties at Tokiwaga Middle School. And for gamers like Hajime Kano, the release of Magic: The Gathering means nothing will ever be the same again!
It's the summer of 1998, Japan. Hajime and Emi enjoy some fun in the sun at the pool and cast spells and summon creatures at their first official Magic: The Gathering tournament...after which, they start to see fireworks-literally and figuratively!
To avoid being late for school on Vamola's first day, Momo takes the mysterious kaiju girl on a shortcut through some off-limits ruins. But the protection spell they perform doesn't work, and she runs into the slit-mouthed woman who resides there!
