Summer is here, and with it oppressive heat, but at least it dries the laundry faster. We meet Isaki’s older sister (voiced by Amamiya Sora), presumably home for break and bossing Isaki around while she luxuriates on a beanbag with an ice cream bar.
Ganta has big plans for an astrophotography training camp to Noto, but the astronomy club has no track record, so it has no funding. Not wanting Isaki to dip into her New Year’s money or ask his dad, he plans to obtain a summer job so they can fund the camp.
That night, Ganta broadcasts a radio show as he uses the telescope’s astronomy software to direct it at the heavenly body of his choosing; in this case the moon. He notes how life has suddenly gotten “pretty thrilling”, and he says what Isaki would say in response to his anxiety about getting a job (“go for broke!) the same time she says it, causing her to fall of her bed head first and get yelled at by her sis.
The next day, Ganta fails his job interview and is down in the dumps, but Ukegawa cheers him up and says it’s all part of the territory. Ganta heads to the arcade to find Yui apparently collapses, but she just overslept after pulling an all-nighter for an upcoming adult gaming event. While she heads to a hot spring to wash up (Yui’s life is my goal) he straightens up the arcade to her surprise.
When he mentions how he needs funding (for what she halfway-jokes is a training camp for his and Isaki’s “secret flirty time), she asks why he can’t just go to his family, assuming he’s rich because he has a high end camera. Ganta tells her his dad always takes things to the extreme, perhaps out of guilt that his mom isn’t around anymore. Yui decides to offer him a job at the arcade, and he’s so grateful he accidentally soaks her.
Isaki and Ukegawa stop by to congratulate Ganta on his new job, but then Isaki is off to the beach with her girlfriends. Predictably, Kana is the one whose heart is set on snagging some boys (or getting their attention and rejecting them gracefully).
Everyone has cute swimsuits, but Isaki wears a big tee over hers…perhaps to hide the scars from her operations? To Kani’s disappointment, there are no hot guys biting, while Isaki, Momo and Anamizu act like a bunch of little kids. Regardless, they’re all having fun.
When Ganta reports to work that day, Yui is relaing in a kiddy pool with shade, a watermelon, and other comforts, simply Living the Goddamn Life. He tells her his planned itinerary for the camp, and she tells him that it will probably cost a lot more than he thinks. She prepares a list for him of what he’ll need so he can recalculate.
As he goes through this list in her apartment, he realizes he badly underestimated the cash needed; even his summer job might not cover it. That’s when Isaki appears seemingly out of nowhere. After her beach trip, where she had no intention of meeting a guy, she decided to pay a visit to the guy she already has!
She also reports that she was hit on for the first time, waits for his jealous reaction, then qualifies her experience: it was grade schoolers who bought her shaved ice.
When Ganta relays to her their club’s dire financial straits and the need to seriously pare down his ambitious training camp plan, she fires the bullet she’d been saving for the right time: her grandmother has a house right smack dab in the middle of Noto. They can get there by bus for cheap, stay there for free, and cook their own meals.
Isaki’s crucial input makes the training camp doable and reignites Ganta’s excitement. In celebration, the two gently put their hands together and start dancing and singing like complete and utter dorks! Like what the hell, why are they so damn cute?! Then again, I get their enthusiasm. They’re essentially going to be playing house together. It should be bliss!
Alas, Isaki’s parade is rained on when her sister announces that she’ll be “tagging along” on her little training camp, presumably as a chaperone. That said, I imagine her sister has normal sleep patterns, which mean Isaki and Ganta should still have plenty of opportunities to be alone together. And oh yeah, take pictures of the stars or whatever. Sure, why not!
