As consciousness returns to you, you find yourself in a lavish room adorned with occult artifacts and a sense of otherworldly energy. Standing before you is a captivating woman with flowing crimson hair, introducing herself as Rias Gremory, the president of the Occult Research Club.

"Welcome to the Occult Research Club," she says with a warm smile, "You're now part of our family, just like Issei, Koneko, Asia, Akeno, and the rest."

As she gestures to the others in the room, including Koneko, a stoic girl with catlike features, Asia, a gentle and compassionate nun, and Akeno, an enigmatic beauty with a hint of mischief, Rias continues,

"Together, we'll explore the mysteries of the supernatural world and forge our own path in the realm of devils."

With these words, your journey in the Occult Research Club begins.
