When Ganta Nakami goes into the observatory, rumored to be haunted, he finds his classmate Isaki Magari sound asleep! They learn they’re both struggling with the same problem.

When another student expresses interest in joining the Astronomy Club, it makes things a lot more complicated for Ganta!

Ganta invites Isaki to the fireworks festival, swearing that they’d only be going together for “photography practice”, and Isaki promptly accepts.

On a cloudy seaside class trip, Isaki makes a promise with Ganta to meet on the beach under the starry sky if the weather clears up.

The heat is unbearable! The lack of AC doesn’t help. Even the breeze is too warm. It's almost too hot to take pictures.

Isaki and Ganta try to hand out fliers at the Shokusai Market for a meteor shower viewing party. Will anyone take them up on their offer?

It’s almost time for summer break! If that weren’t enough to be excited about, the Astronomy Club plans a meteor shower viewing party.

After the viewing party was rained out, Ganta plans to shoot pictures of the starry night sky and then use them to enter a contest.

Despite starting a part-time job, Ganta hasn’t raised enough money for training camp. But thanks to Isaki staying at her grandmother’s house, their problems are solved.

On the second day of their training camp, Ganta and Isaki’s adventure begins with a trip to Mitsukejima.

With their chaperone Haya now gone, Ganta and Isaki are left all alone at her grandmother’s house.

Isaki’s parents find out that she and Ganta have been staying all by themselves. Naturally, they demand that Isaki come home right away, but she refuses.
