Aoi spends most of her time alone, but an old friend from middle school has arrived to make good on an old promise.

With the help of Hinata's dad, the girls familiarize themselves with the necessary gear to climb.

Hinata convinces Aoi to try climbing a mountain, but Aoi thinks they should start with a small mountain and work their way up to the big ones.

Aoi and Hinata have a camping cook-off.

Aoi meets a girl from her school who is crazy about backpacking.

It's Aoi's turn to pick the mountain, so she calls on her new friend to help.

Aoi picked the mountain but now she needs the right equipment.

Aoi and Hinata embark on their second climb and meet some interesting people along the way.

Aoi and Hinata put up a real tent in Hinata's yard! Afterwards, Kaede and Kokona join them and they cook a meal outside together. They camp in the tent overnight and get excited about climbing mountains soon.

Aoi buys Hinata a gift, but Hinata’s mind seems to be elsewhere. Meanwhile, Kaede makes plans for the gang to climb Mt. Kinpu on an overnight trip.

The mountaineering club is a lot of fun, but not everyone was into the idea at first glance. Some people need a more comprehensive introduction!

A trip to Naguri Lake? Sounds like fun, especially since Aoi gets to try canoeing with her coworker. But does this outing feel a bit…unusual?
