It's a TRAP! Well actually it's not technically a trap so much as just a magically transforming person. Poor Natsuru wakes up one morning to find himself just a bit different than from when he went to bed. Not only does he find out that he's been turned into a full on girl but his Entrails Animal plushie is able to talk now and tells him this wicked little story about how he has become a blue Kampfer and how he must fight the red Kampfers and the only way he can do that is as a girl thus unlike the other Kampfers who just change a little bit when it's time to fight Natsuru turns into a girl. And it only gets better from there.
Soon Natsuru meets up with two other Kampfers another red and a Blue who turns out to be the School's President who makes Natsuru remain in his female form and attend the girl side of the school where much yuri lusting happens.
Of course Natsuru doesn't know quit what to make of all the new attention he is getting as a female but he has found out that his boyhood crush Kaede wants him badly which is nice but she doesn't care much for the boy Natsuru. This is of course a problem for Natsuru as he wants Kaede to like his boy form. The fourth Kampfer turns out to be Natsuru's long time childhood friend who has just gotten back from traveling the world and an all out girl fight for Natsuru ensues with Natsuru only having eyes for Kaede though it's tough sailing for the other girls.
The girls have formed a timid truce between the two groups and lead by the Student Body President. They did this in order to find out why they need to fight which turns out to be a lame attempt for a planet far far away to settle their own problems. The moderators of course are not happy about the truce and Kaede goes into action to fix the problem at first trying to use Natsuru as a boy toy to keep the Pres busy and kick her out of the game. Since that didn't work she creates the white Kampfers to finish off the two groups only that doesn't work out either as the white Kampfers are beaten and the run off leaving us with a soft climax to the story and an open ending.
The very last episode is more like a DVD special as it has nothing to do with the story and is a body swapping special this time around the girls switch bodies with their respective Entrails Animals and hilarity ensues. I liked this series a lot and yeah it has a very descent amount of fanservice (more likely in the DVDs) but it's also pretty funny to watch even if it's nothing that serious or ground breaking. I do really want of those entrails animals though.
