Gate 7
Summary
From Baka-Updates:
An innocent sightseeing trip to Kyoto opens up a magical realm to shy high schooler Chikahito Takamoto. Visiting a legendary shrine, Chikahito finds himself in the mystical world of Hana and her comrades—and his immunity to their powers leads them to believe that he’s no ordinary awkward teenager! Protecting our world from violent elemental beasts, Hana and her team welcome the confused Chikahito—who isn’t quite sure that he wants to be caught in the middle of their war! One thing’s certain, though: since he’s smitten with aloof, childlike warrior Hana, he’s along for the ride, for better or worse!
... and the second season of the Anime did a better job of pacing than I thought they would. I think they moved the Elf village arc from before hostilities with the Principality began to the inter-war period, aka the start of the second season, and used that to pad it out. Good call if that's what they did. In any event. Good season.
