After catching up to latest chapter of this manga, I can gladly say it is on the right track.

STORY
I am really enjoying the story at this point in time. Iris Zero thus far is a supernatural story that focuses on a protagonist who is anything but supernatural. Toru is one of the 1% of the population born as an ordinary person and because of this, he faces discrimination at school everyday. It reminded me of Hana Yori Dango a bit with the amount of indirect bullying that goes on but less angsty with a touch of drama, mystery and romance. It isn't dark but reveals the consequences of having an Iris. What makes the concept for this story strong is how it works with Irises as plot devices and the development of the characters.

ART
The art is above average, neither stellar or terrible. The panels communicate what they need to without confusion for the most part. The character designs are okay as well.

CHARACTERS
I think this is one of the other areas where this series truly shines. The way all the characters interact together, Irises included, is fascinating to me. You really believe in the insecurities and troubles of each character and empathize with them. Toru's perception and keen ability to analyze are engaging to follow throughout the story.

OVERALL
Really loving this series so far, 5 volumes and 22 chapters in. Hope it goes the same route as it has thus far. I just it was over so that I knows what happens next.
