You can't really take this manga seriously. If you do, I think you'll be incredibly freaked out. It starts out semi-normal (for a supernatural manga anyway), but it quickly progresses into this weird stalker-possessive story whose heroine I just can't support. I understand that she's kind. But she's seriously going about it the wrong way…. though that might just be because she's stupid. If she just confessed directly and got to know him in a normal way, we could have a supernatural comedy instead of what I see as a undercover horror story for our MC.
Let's just say she takes to have the spirits watch (yes, that's right, WATCH him) every day. She therefore can stalk him and appear in random places (and bless his heart, he only thinks it's a little strange, as opposed to obsessively creepy---he's obviously dense). She also unintentionally wreaks misfortune on his life, but either doesn't realize the effect (an idiot) or refuses to allow him any means of protecting himself (an obsessive psycho).
What really pushed me over the edge was in the latest (scanned, I would never bother trying to track down raws for this manga) chapter, when Inaba-kun found a way to protect him from spying spirits (i.e. they could not enter his place as they pleased), she not only found out but destroyed the way he could protect himself from spiritual stalking. <---- This is creepy. And the result of this is that she limited her spiritual stalking to once a week.
You have got to be *****ing me.
I think I know why this is set toward a male demographic though… because she's cute, all the creepiness is somehow excused. I don't really find stalking funny in anyway at all as an expression of love…. especially when it has such a huge negative effect on his life. I get that he's the first real friend she's able to have. But shouldn't you treat your friends kindly…?
In sum, this manga is definitely borderline creepy.
