Once a Butler, Always a Butler

Once a Butler, Always a Butler. As the title suggests, he is a butler. A servant. Someone who serves someone. Serving tea, taking care of his mistress's needs and demands, taking care of the house are all part of a butler's job. Sounds easy, right? Carefree life where his only worry is his mistress's business. But is he any normal butler in a normal household? ***************** Warnings: - This is NOT a Crossover between Nisekoi and Dxd. - This fanfic has two parts - his first life (Nisekoi world), and his second life after he died (DxD world) - The MC will be a peerage servant, so if you hate those sort of things, please don't read this. - This will just be a side project. Don't expect weekly updates. I'll only do this when I feel like it.
