Another wacky comedy from Hijiri Ringo-sensei. It's the story of four sisters who are twins, and their names are Haruko, Natsuko, Akiko and Fuyuko (no creativity whatsoever there). Each of them have their own special 'skills', like martial art, high intelligence, etc. They run a detective agency, with everything in the firm taken care by themselves including the many times dangerous investigations. They do get customers, but somehow they keep on having serious money trouble...

If you look at the picture then you might think the artwork is not pretty bordering ugly. Well I think so too. But this is really just a gag, a hilarious and crazy manga that Hijiri-sensei's mastering at, and the artwork totally gives advantages and not the other way around. There are really not many manga like hers, a must read for bold comedy genre.
