Shu Susuki is a laid-back student whose top priority is looking cool, even if it means getting pulled away for a lecture every now and then over his pierced ears and dyed hair. Imagine his shock, however, when it turns out he's been totally outdone by Yahiro Tsukimi, a straight-A student who has piercings in some pretty extreme places… just ones that are easier to hide from the faculty. Shu's dying to know how deep the rabbit hole goes and and approaches Yahiro for answers, which leads to the two bonding over bodymod and developing an unlikely rapport. When their discussions end up giving Shu glimpses into Yahiro's daredevil side, his curiosity and concern ends up drawing him deeper into the other boy's life than he ever imagined. **Official Translations:** English ([Irodori Sakura](https://sakura-r18.irodoricomics.com/Scrumper), [Renta](https://www.ebookrenta.com/renta/sc/frm/item/148080), [Coolmic](https://coolmic.me/titles/5230)), [T.Chinese](https://sakura-r18.irodoricomics.com/Scrumper-TW) **Original:** Japanese ([cmoa.jp](https://www.cmoa.jp/title/283328/vol/5/))

*Vol.1:* In a shattered world where power is scarce, the future of humanity lies with the Filaments: rare mutants who can act as human generators by converting emotions into electricity. Saneyoshi has just been elected as a caretaker for a Filament named Kaguya, a smug pretty-boy who's far from shy when it comes to his preferred method of creating power – lots and lots of sex. But Saneyoshi's inexperience with intimacy leaves him feeling like his civic duty is far too heavy for him to bear. Can he step up to the plate to keep darkness from swallowing the city? **Official English:** [Irodori Comics](https://sakura-r18.irodoricomics.com/Light-Up-My-World-1), [FAKKU](https://www.fakku.net/hentai/light-up-my-world-1-english), [Renta](https://www.ebookrenta.com/renta/sc/frm/item/148592), [Coolmic](https://coolmic.me/titles/6438)
