Well, it has the same basic concept of Sm, teenagers that can transfor into heroes, only it goes deeper than that. Emotions run high, characters betray each other, people lie and decieve all while a strange evil force tries to take over the earth. People fall in love, and roance abounds. The first three girls mentor is a petty, snobby, british-accented woman with red hair in that freaky loop-dee-loop anime style. The strange evil is the greatest ever know and is also the greatest threat ever know.
Can't say much more than that....
