If you want to laugh, cry, have your heart warmed, and maybe even learn a thing or two about navigating this weird ordeal we call life: this is the manga for you.
If you just want to read a fun manga with good art and great characters, this is also the manga for you.
I won't try to describe Life-man any more than I already have, because there's no way my words would do it justice. I easily rate it 100/100, and in just 35 short chapters, it's made it into my top 5 manga of all time. Do yourself the favor of giving it a read.
