So... you're a perfect candidate as a Sabbath "onii-chan", with your bodily physique and charm. The Demon Lordess herself, impressed with your appeal, wants you to go to work right away... but doesn't know where among the Sabbath selections to put you in.
Therefore, the Demon Lordess wants you to choose the Sabbath you like most, state your reason why.. and what would you do once you are in it.
WWYD ! (GO !)
