Date or die!! Get naughty or humanity is done for!
It's Mutsumi's turn to step into the spotlight! The soft-spoken Valkyrie finally gets to go on a date with Takuma, but idols are under a strict love ban-no dating allowed! That means they're gonna have to go incognito if they want to gain enough experience points to level her up. Will they be able to stay under the radar, or are both Mutsumi's idol career AND the world doomed...?
