Lin Ming has been in this world for sixteen years, always believing it to be an ordinary one. He copies novels, saves up small amounts of money, and dreams of a simple and happy life with female seniors on his left and female juniors on his right.

It wasn't until he stepped into Kuoh Academy and saw Toujou Koneko's cat ears, Himejima Akeno's lightning, and Rias's destructive magic... that he realized with despair that this was "High School DxD," a place where people could die! The aftershocks of the mystical powerhouses fighting could obliterate him.

In a moment of crisis, the Infinite Dimensional System awakens: Afraid to become stronger? Newbie quests force you to make extra-long confessions to three popular heroines! Too afraid to take risks? Then traverse countless worlds for forced training!

Kiana: "You mean Xiao Yu? That guy's such a blockhead! I can't believe I like him!"

Mei: "Brother Xiao Yu, he's a very reliable senior, it's just that there are too many inappropriate people around him."

Bronya: "Brother Xiao Yu is very skilled at gaming, but he seems to have some heavy past."

Xilin: "Don't you even know what 'first come, first served' means?! Get out of my Xiao Yu's way!"

Bell, Yegorlitt, and Berleon: "Let's not get involved."

Beneath his feet stretched an abyss of black legions. Cheng Xiaoyu stood high above, overlooking the battlefield. With a wave of his hand, boundless shadows enveloped the entire area.

"Stand up"
