I Saved Too Many Girls and Caused the Apocalypse: Volume 13

It's fall, which means it's time for Mitsuhashi High's annual school festival! Things are special this year because it's being hosted in conjunction with Hibiki's school, which means extra fun... and extra work. President Momone ropes Rekka into helping with the festival preparations, which turns out to be more than he bargained for when they get sucked into a video game world. Then there's the bomb threat, the duel, and... Only one thing is for certain-this is going to be a festival to remember!
