Akuma-kun

Ichiro Umoregi is the second Akuma-kun – adopted by Shingo Umoregi as a little boy, Ichiro is meant to be carrying on his father's work of bringing about the utopic Millenium Kingdom. But Ichiro has a difficult relationship with his dad and despite the sometimes desperate attempts of his cousin Mephisto III, Ichiro just kind of trudges through life. But when a strange angel from his past appears, Ichiro is forced out of his torpor because sometimes the world really is worth preserving.
