Hidden is a scout who joined the hero's party to defeat the Demon King. But the hero, Ashram, and his party members did not know anything about the fundraising, the spies sent by the Demon King, or the assassins sent by the rebels.\r\n\r\nDeciding to support from behind the scenes, he took on all of the dirty work for them.
