People in Zongman, Double Penetration Godkiller

Luo Guang traveled to a holographic world that blends the worldviews of DXD, Jujutsu Kaisen, Dark Rally, and Ghoul.

After his body became smaller, he didn't awaken his cheat code until he was twelve years old. As long as he practiced, he could continue to become stronger, and he was also given a portal function.

Of course, as a time traveler, he naturally couldn't be without a novice gift package. He started with the demon-slaying holy sword Esther, which could kill enemies and warm the bed.

Soon, Luo Guang became stronger, but he didn't go bald.

Rias: "Rias, Rias, how can you be so stupid."

Shichito Sona: "Listen to me, thank you..."

Esther: "I was here first!"
