To avoid being late for school on Vamolas first day, Momo takes the mysterious kaiju girl on a shortcut through some off-limits ruins. But the protection spell they perform doesnt work, and they run into the slit-mouthed woman who resides there! The two narrowly escape, and its only later that Momo realizes the real danger they were in. So why is it that for Momos own safety, Seiko is now forbidding her from leaving her room after 10 p.m. for the next week?!
