The third episode of the series titled "Fomalhaut - Piscis Austrinus" immerses the viewer into the rich, distinctive world of Ojiro Makoto, with likable characters and captivating themes.

The episode begins with Ganta taking on the role of club president, a responsibility he takes very seriously. To secure the future of their clubhouse, Ganta and Isaki must establish a legal club, which means securing funding and attending meetings. Their helpful teacher, Kurashiki-sensei, instructs them to meet the last active member of the club, Shiromaru Yui.

After a journey through rural Ishikawa, Ganta and Isaki come across a lively gaming center called "Betty," run by Shiromaru Yui herself. The addition of Tomatsu Haruka as Shiromaru Yui is a fantastic choice that further elevates the series. Shiromaru introduces the two to the world of astrophotography and stars, igniting their fascination and passion for the subject.

Ganta's natural affinity for technology and tinkering serves him well as he delves into the complexity of photography, especially when it comes to astrophotography. The joy he experiences when taking his first star photo is contagious, and Shiromaru is more than happy to share her passion with him.

Though it is a relatively short slice-of-life episode, the warmth and sense of adventure are palpable. Ganta proposes a Perseid meteor shower viewing party as the club's main event, and Kurashiki encourages him to participate in a student astrophotography contest to win the school's support.
