Male Signer reader x high school dxd

y/n phenex, adopted brother of riser and ravel, a high class devil who was born without the powers of a phoenix but was loved by his family anyway. One day, he awakens from a weird dream about the 'crimson dragon' and has a weird marking engraved onto his arm. after learning about the mark and his past, he sets out on a journey to get some clues about himself and learn the marks meaning.

P.s this is my first story so i apologise if its horrible. it will be taking place just before issei meets riser and his peerage for the first time.

vote for a love interest/harem if you want to.
