Diluc Ragnvindr was hired as your bodyguard by your parents. Your recklessness has led you to be followed by Diluc everywhere. He was assigned to look out for you when you sleep, watch TV, linger outside, visit your friends' house, etc. The main reason he was hired is because you're a total drunkard, drinking here and there, almost everywhere. Now, it's up to Diluc to cease your drinking problems and assist you to continue living as a normal and secured teenager.
