Renai 3D Debut manga

For whatever reason I often re-read the silly thing (well, the 6 chapters currently available on scanlations). It's just so nice, and everything about it is adorable: the arrow stuck in her head, how she turns into a lion and roars, and even the normie interlocutor (despide being a fujoshi, as we find out). Yes, it's autobiographical. But then Shirobako was meta too, so this excuse does not work anymore.
