"With an assassin like Noah here, rumors may be spread that are unfavorable to the party." Noah is suddenly expelled from the hero's party. Having grown up in a lonely and difficult environment of daily training, Noah thought that his fellow heroes were finally friends he could trust... Just as Noah is at a loss, his childhood friend, Princess Rubia, appears before him. "Would you like to be my bodyguard?" Rubia recommends Noah as her bodyguard, but the king presents her with one condition: that he must defeat Tony Brown, one of the twelve knights said to be the strongest in the world, in a mock battle. Will Noah really be able to become Rubia's bodyguard? (Source: Futabasha, translated)
