There's more to this that hasn't been scanned. The current version ranks a 2. Hopefully someone translates the rest one day so I can put that rating up.
there was a duplicate panel, the complete scan isn't available, the understanding of the plot was poor so unless the other chapters would make up for it which we cant read. i dont even know how to continue. so yeah. not even gonna give this one a rating.
Confusing translation, but somehow probably not great writing either... Vampire that's allergic to humans (but still craves for them), in his thirst, seduced a man who the next day is extremely frustrated with him when nothing happened between them that night. Instead, the man teaches the vampire to be with him "the human way", which surprisingly doesn't trigger an allergic reaction.
Someone said that there are actually 10 released chapters, but it seems only the "pilot" oneshot is uploaded here.
