Celestial Bane 2 was a novel. There were different explanations for why the characters were always in combat mode. There were several possible explanations: 1. The character is in combat mode because they are fighting an enemy. In battle, the character will always be in attack and defense mode to fight the enemy. 2 characters are in combat mode because they are executing a mission. In some situations, the character may be in a constant combat state, such as when performing a mission or protecting someone. 3. The character is in combat mode because they think they must remain in combat mode. This could be because the character was undergoing some kind of training or self-enhancement to improve his combat ability. The reason why 4 characters are in combat mode is probably because they are forced into combat mode. In some novels or games, characters may be forced to fight all the time to protect humans or other characters. These are just some possible explanations. The specific reasons may depend on the plot and setting of the novel.
