Technically it's not brother complex but yeah this kind of relationship is as shonen-y as it can get, so meh.
Been faithfully following the scans since day one. Can't say I've been impressed
with the series until these past couple of chapters. I'm actually disappointed that it's more of a shonen with horror elements rather than the other way around.
Soooooooooooooooo
Smooth Criminal
For me it's the other way around, seeing as the raw drawings gave the manga much more tension and atmosphere, and I'm unimpressed.by the last few chapters.
By the way while we're talking about scans everyone should go read One Punch Man and/or Mob Psycho 100. You may or may not be bothered by the drawings, but this guy right here is the author of the century.
OPM is easily my favorite manga right now, and the fact that it's getting a remake by the guy that made Eyeshield 21 makes the whole deal even more epic to follow.
