"Kiba was acting weird he knew about the sword in the picture," Issei thought to himself, "Goku said he'd teleport to me just to check in." Issei kept peddling to his location.
He rang the doorbell and a man with yellow hair with black hair overlapping it opened the door. The guy looked at a foreigner wearing a dark purple robe.
"So you had to bike here?" The foreigner laughed, "You're a devil who does contracts and your bike here." As he laughed at Issei's hopelessness Goku appeared out of thin air.
"So I don't assume you're a devil?" The foreigner asked, "No, but how did you figure it out?" Goku questioned like a curious child, "When the devil teleports a red circle comes beneath them."
"Well anyway you see that picture, It's not a reproduce, so can I pay you that?" Issei started, "well" as he cut him off he responded, "or I can pay you, my soul." Issei cut him off, "No that won't be necessary."
After that was done Goku and Issei left the nice apartment. "Issei hold the bike and painting" Issei held the bike and they teleported right in front of Rias.
"Goku, Issei! How was his first mission?" Goku just laughed "The guy was laughing at him for taking a bike. I told him I could fly him to the place."
"So we got a painting." Rias would laugh "That's good but we need to fight a stray demon." Issei, Kuba and Koneko would walk into the factory as a demon that had bug-like features would drop down, pinning Kiba.
Koneko grabbed the demon and threw it into a ceiling window as she said "blast off." The demon crashed throw the ceiling windows as Goku punched it even higher as a lightning bolt came down.
It dropped to the ground chard and nearly lifeless. "Should I send it back to hell", Goku asked as Rias nodded. Goku would charge up a kamehamehameha and would erase the demon.
"Goku that was so cool, teach me that." Issei would beg "Maybe, Issei" Goku chuckled as Rias would walk up to Kiba and slapped him.
