1 Your luck sucks!

...As Issei was dieing on the ground, he wished to see his senpai, Rias Gremory, one last time.

Issei's day has been wild, from getting a girlfriend to getting murdered by said girlfriend it was safe to say that it has been an emotional rolercoaster.

As Issei closed his eyes for the last time, Rias Gremory apeared, summoned by Issei's desire and the devil panflet he'd happened to get on his way to his date.

Rias confronted Raynere, Issei's girlfriend/murderer and sent her packing, but when she turned to heal issei, she realised she was too late and Issei was dead.

Filled with regret for not arriving sooner, Rias decided on an impulsive decision: To reincarnate Issei as a devil of her pearage.

After using all of her pawns, the cerimony was complete and Issei was breathing again, even if he was not a human anymore.

As Rias was preparing to send the still unconcious Issei back home, she felt a change on the boy.

As if another human soul had entered his body and started to merge with issei's now devilish soul. This baffled Rias, but it was nothing compared to what happened next.

A beeing apeared next to them. No magic circle, no magical presence, nothing!

If Rias was not staring at the beeing, she would think there was nothing there.

"Man!" The beeing said looking at Issei. "You were not joking when you said your luck in gacha sucks mister John. To transmigrate as Issei of all people, and just as he becomes Rias' slave!"

"Hey!" Rias exclaimed insulted. "I don't know what is going on, but I have you know that-"

"-That you treat your pearage as family." The beeing interrupted. "Gremory-san, it may be shoking news to you, but a well treated slave is still a slave. "As for what is going on... Well you know the isekai trope, so this will be easier to explain." The beeing said, much to Rias's confusion. "I am what you call a ROB, and the soul that possed the body of Issei here is a transmigrator called John." Rias' eyes shone.

Rias was an otaku through and through, so the idea of her having a transmigrator in her pearage almost made her die and reach otaku heaven. "Does he have a cheat? What is his world like? Does he have foreknowlage? Does he-" Rias exitedly question the ROB who sweatdropped.

"Calm down lady. This all will be up to John wheter he will tell you or not. I am just here cause I pity him and will give him a little cheat." ROB said and waved his hand towards Issei/John. Nothing seemed to happen, but beneath his eyelids, Issei/John's eyes went through a transformation. "Tell him he got the deva path of pain and the chakra to go with it, but NO OTHER PATHS! This is very important."

The ROB then said goodbye and disapeared.
