Gate 7 Volume 2
A strange dimension overlaps with our reality, sending magical creatures and bloodthirsty spellcasters against the Earth's protectors. As the newest member in Hana's group, awkward high schooler Chikahito Takamoto is looked upon with puzzlement and suspicion by his older teammates. They don't know how he can be immune to their powers, or if Chikahito has any latent powers of his own. Finding himself in the middle of this mystical war, Chikahito tries to make sense of his quirky, moody allies and his own feelings for Hana-a strong, short, and awfully cute warrior!
