Ep 7. I Get a Familiar!

Issei and his friends are practicing for an upcoming school festival when they come across a mysterious girl named Asia. She introduces herself as a nun and asks for Issei's help after being chased by a group of stray devils. Issei quickly agrees to protect Asia and takes her to the Occult Research Club to seek refuge.

Meanwhile, Rias and the other members of the Occult Research Club receive an assignment from their Devil employer. They are tasked with saving the souls of a certain group of humans who are being targeted by a dangerous Fallen Angel named Raynare. Raynare has been using her powers to seduce and then kill the humans, and it is up to Rias and her team to stop her before she does any more harm.

As Issei and Asia become more acquainted with each other, they start to develop feelings for one another. However, their budding romance is put on hold as Rias and the others call upon Issei to help them with their mission. They need Issei to use his powers of the Boosted Gear in order to defeat Raynare and save the humans from certain death.

The team sets out to confront Raynare, but upon arrival, things take a turn for the worse. Raynare reveals that she had been posing as Asia all along and had manipulated Issei's emotions in order to get closer to him. She then proceeds to attack the group, leaving them severely injured.

In the midst of the chaos, Issei discovers a hidden power within himself that allows him to summon a powerful dragon. With this newfound power, he is able to defeat Raynare and save the souls of the humans she had targeted.

As the episode comes to a close, Issei and his friends regroup and tend to their wounds. Issei's feelings for Asia are now stronger than ever, and the team begins to recognize his increasing potential as a Devil. As they prepare for the upcoming school festival, they know that their battles are only just beginning.
