i just found this out after uploading this, but manose is making another manga right now about music. he's the writer this time, and instead of doing the art (sadly), "Miharu" is the artist! if you wanna check it out, its called "Island Rock / Shima Rock"
the world starts to heat up so much that the sky is left permanently bright outside if i remember correctly, most likely due to the overuse of electrical supplies, so much so that everything starts to fall apart as people chaotically turn to Hikaro to survive. more and more people start to die...
i'm enjoying this, but the painful moments hit hard. i really hope ao isn't dead and he appears soon so nezumi can stop being so sad. it makes ME sad seeing such a sight
