Reishou Suzuya/Relationships

Through out most of his life, Rei has made many friends and companions through out his life, but his true bonds are found with the various characters of the cast of DxD, notably those in the Occult Research Club, the Student Council, and others involved in the affairs of the Supernatural World, such as the Church.

Rias Gremory
Rias was originally unaware of Rei up until halfway into his first year, which, at that point, had begun to involve nearly all of the first year students in his escapades. When they first met, their relationship is more or less cordial, and strictly between kouhai and senpai.
