What If You Had a Golden Experience in Everyday Life?

After failing in his previous life to save a driver trapped beneath a burning tanker truck, then getting blown to pieces, Qiao Rang transmigrated to a parallel world and became one of the children at Cat Guest Orphanage. He thought this life would pass peacefully, but one day he suddenly saw a busty vampire with blonde hair and blue eyes! She even claimed to be his elder. He had no idea why Dio had become Diona, but if this blonde bitch was just so chuunibyou that she was making things up, he could let it slide... except there was a girl named Kujo Chengzi chasing after her, trying to kill her! Qiao Rang: Can I team up with you to fight Diona? My [Gold Experience] can hold its own, too. Fighting wicked vampires alongside Ripple warriors, becoming the man behind a Valkyrie fighting team, rising to the top of the Kengan underground, and resolving the chuunibyou supernatural troubles of certain people at an apparently ordinary school... And so, Qiao Rang's daily life began. Note: This is a crossover series with multiple heroines, including but not limited to JoJo's Bizarre Adventure, A Winning Bet, Kengan, Rascal Does Not Dream, In/Spectre, Sankarea, and more.
