Surprisingly, aside from the de-aging pill, the manga manages to be completely unlike any high school setting I've seen or read thus far in its maturity. The subjects the character deals with and how he affects his new ReLife friends are handled very well, with life lessons that most definitely have real-world applications.
It is currently one of my favorite manga so far, as it's managed to impress me with its mature handling of high school situations. There is no fan service or ridiculous high school hijinks, which is always a plus. The manga is in full color, too.
It will be receiving an anime adaptation in 2016, which is entirely deserved, and though the manga hasn't been completed yet, I recommend anyone interested in a maturely-handled high school story to read ReLife.
