Episode 13 is a direct continuation of the series and takes place the day after the final battle with Kampfer Kaede and her troops. The girls are taking a bath while the Pres is getting some quality alone time with poor ol' Natsuru who keeps turning into a girl or boy at the wrong time. Not that the other girls mind they'll do him/her either way.
At school the next day All of the fighters run into each other and it seems like the regular Kaede doesn't have any recollection of the events that transpired the other night and leaves the blue and red team to wonder if Kaede is a moderator or just being controlled by one. With the Pres getting a head start over Mikoto and Akane they decide they need to try something and do a bit of kissing practice with each other and go a bit over board with each other. Best kiss this year in a none-hentai show for sure.
The white team has a great little bit of excitement including introducing a new entrails animal the tsundere penguin that is able to hypnotize Mikoto to assault Natsuru and fight the other blue and red girls even though she knows what is going on she can't control her body. Well that is until the Pres gives her a shocker to snap her out of it.
A battle ends the show with the blue and red kampfers fighting the white kampfers. The battle ends on a draw and everyone retreats. Kaede gives the white kampfers a nice present for their work well done whie the others run off chasing after poor Natsuru again.
Episode 14 is the bonus extra episode that doesn't have anything really to do with the series and is an episode that takes place in a "hostess bar" as Natsuru needs some extra money to buy a new bra since her chest keeps growing. The great thing about this episode is that it's entirely fanservice and humorous and doesn't have the same amount of violence as the series did. This is the guilty pleasure episode at it's best.
All I have to say is that these were a couple of fun little extra episodes that just makes you really want another season of Kampfer.
Check out on of the many trailers for these two extra episodes.
