Zettai Heiwa Daisakusen

Zettai Heiwa Daisakusen (or Battle of the Peace in English) is a shojo manga focusing on prince Johanne and princess Euda from the two warring countries of Meteora and Cannan/Kanan that decide to pretend to fall in love with each other to end the long war. While they appear to be lovey-dovey in public, they can't stand each other, but have no choice but to go on with the engagement if they wish to keep war at bay. However, Euda seems to be slowly falling in love with the prince that she originally despised, even though she denies to extremes and sees her racing heart and inability to look Johanne in the face as signs of hatred. In addition to these feelings is the constant threat of terrorists who wish to continue the war and kill either Euda or Johanne, whom they feel are traitors to their countries for marrying the other. There is currently one volume out in Japan. See here. ---

Provides Examples of:

 * Arranged Marriage
 * Aw, Look -- They Really Do Love Each Other: And how!
 * Belligerent Sexual Tension: A very diluted version, with Euda being a Type B Tsundere, and Johanne being a very mild Jerk with a Heart of Gold.
 * Big Brother Instinct: Zacaria and Ishmael are very protective of Euda, although it has yet to go to extremes. Euda's sisters on the other hand...
 * Big Brother Mentor: Rafael to Johanne.
 * Bratty Half-Pint: Johanne sees Euda as one of these at first, since she's always running away from him.
 * Breaking the Fourth Wall: Done slightly in Chapter 7--although not to the audience--when Rafael tells Johanne that if he keeps on protecting Euda, he will get killed. Johanne tells him not to raise a death flag, or a sign to the audience that a character will die in the future.
 * Cannot Spit It Out: Averted with Johanne, who says from the start that he likes Euda; Euda's having trouble on her end, though.
 * Cannot Stand Them Cannot Live Without Them
 * Damsel in Distress: Euda, despite all her efforts to fight back and even learn self-defense, seems to fall under this trope.
 * He Is Not My Boyfriend
 * Slave to PR
 * Spell My Name with an "S": Is it Canan, Cannan, or Kanan?
 * Tenchi Solution: It is revealed early on that Euda's father has 4 wives, which led to him having twelve children, of which Euda is the only girl.
 * Tsundere: Euda is type B.
 * What Is This Thing You Call Love?: Euda to a T; she thinks her racing heart and inability to stare Johanne in the face are signs of hatred.
