This is one of the gems that never came out outside of japan...and that's a shame because this little action platformer is actually pretty good.
You play as Mikami, the head of a ghost hunting team, and you set out on various missions to solve mysteries involving monsters and ghosts.
More like known titles such as Castlevania or Ghost'n'Goblins, Mikami can find weapon upgrades, special moves and other stuff to help on her quest. The stage are classic action platformers levels, Mikami has the ability to hang on certain platforms and then climb up, this gives a little "different" touch to the standard level designs that you may expect. 
At the end of each stage there's a big boss fight, for every boss you beat you get a gem. After you collect all the 6 gems you are able to fight the final boss.
I liked this game, unfortunately it's a bit too easy, good players can beat it straight on the first try, but it's still fun and addicting.
