Just an all around "fun" manga to read. Right from the first chapter, you're thrown into a sort of confusing "should he really be doing this" type of experience. The main character, Suekichi is presented with a very "weird" and "random" girl who seemingly just wants him for his newly found (but can't quite get) family inheritance. So, let's roll out what I thought of it all.

Story:
Suekichi's grandfather passes away and he is left with the "future possibility" of claiming 450 billion yen if he graduates from college. But wait, Aya, a girl whom he finds lying next to him after his grandfather's funeral seems to want this money for herself. Can having sex with Suekichi really win him over that easily, or is there more to what she feels for him?

The story is funny, it's not very predictable, and there's a pleasant ending.

Art:
Really old school artwork. I didn't like it a lot, but not a lot to complain about.

Character:
Picture yourself in college. Suekichi is basically any ordinary guy that's trying to make his way in the world. The girls aren't stupid, and it's not a "we all love Suekichi show", so you'll probably like most of the characters.

Enjoyment:
Very enjoyable. Not really much more I could have asked for. You'll laugh a lot, and you'll ask yourself a few questions about what you'd do in certain situations.

Overall:
Give it a read. If you like comedy, nudity (sex scenes), and a good plot, you won't be disappointed.
