Thanks for the invitation. I'm in One Piece, and I start out as Black Hairless.

Wandering the seas, free and unrestrained, but—

Why is this eagle-eyed rascal chasing me around all day? What? My son offended you? Then go find Xiao Mo! Why are you bothering me?!

Garp, why are you chasing me every day? Huh? Where's Great Britain? Can't you find it yourselves? Inviting me to join the navy? Me, the King of Great Britain, are you kidding me? No way!

Redheads? Giving you face? Not getting involved in the summit? Giving a cripple the run for his money! Asking for a beating!

Huh? I'm not that Black Hairless guy! What does your looking for Black Hairless guy have to do with my Gundam? You've got the wrong person!

Traveled through the Douluo Continent and became Dai Yunhan, the fourth prince of the Xingluo Empire.

At the beginning, Zhu Zhuqing arranged a marriage for Dai Mubai?

How is that possible? I am also a prince, so my wife must be Zhu Zhuqing!

Haha!

Mine, mine, all mine!

Li Yuan transmigrated to the primordial world and became a mediocre innate deity—[Eternal Evergreen Soar]—and obtained the cheat code [Seed of Cause and Effect].

At the end of the Great Calamity of Longhan, everyone was bloodthirsty and killing each other, but he was secretly doing landscaping.

Demon Ancestor Rahu intended to destroy the West and perish together with it, but Li Yuan preemptively patched the earth's veins with "life patches".

After the explosion, Hongjun stared blankly at the partially shattered Western Paradise, yet Heavenly Merit surged towards Li Yuan. Hongjun now owed Li Yuan a great karmic debt.

From then on, Li Yuan lived a happy life in the prehistoric world, deceiving fellow Daoists and fleecing the Heavenly Dao.

Li Yuan: Hahaha! Merit? Oh my, it's all mine!

"Huh? Where did this merit come from? Never mind, I must have made a huge contribution! Thank you, Boss Heaven, for the salary!"

Heaven's Way: ? ? ? It's you again?

What would happen if you replayed the story with your max-level account? Gudako looked at the dazzling array of Servants on the Silver White Servants and clung to their thighs. "Please carry me, boss!" Black Saber stared wide-eyed at Morgan from the Lostbelt. "You are! My sister!" Jeanne d'Arc looked at Metatron Jeanne lazily leaning against the Silver White Servants and vehemently denied it. "This lazy guy isn't me!" Nero stared at Draco, the Sixth Beast, in front of her, stunned. "You mean, this human evil is Yu!" The Silver White Servants arrived at the Grand Temple of Time, with Draco on their left, Ereshkigal on their right, and the Director of Unbeast behind them. "Goetia! You're not at the Grand Temple of Time! Where are you!" System, harem, mindless, lighthearted, a little bit of romance, slow pace.

Carter transmigrates into Garp's younger brother, only to marry Linlin right from the start, and from then on, they live a shameless life of having children. 50 years later, Luffy sets sail! Zoro: "Luffy, run! That's Admiral Entei!" Luffy: "It's okay, that's my uncle!" Nami: "Luffy, run! That's Yonko Thor!" Luffy: "It's okay, that's also my uncle!" Usopp: "Luffy, run! The god of Skypiea is here!!" Luffy: "It's okay, that's my aunt." Until one day, Blackbeard comes knocking! Luffy: "Everyone be careful, this guy is a Yonko!!" The Straw Hat crew: "Tell me, which uncle is this?" Luffy: "He's really not!" !!!

Yuu Tōsaka, the adopted son of the Tōsaka family, later went to the Clock Tower for "advanced training."

After opening it, he entered the game's world and encountered Tiamat right at the start. [Quest: Fight alongside Tiamat] "Wait, why aren't you asking me to save Humanity?!" Yuu Tōsaka quickly discovered his blind spot, but he ultimately successfully completed the system quest and spent a wonderful time with Tiamat. ...After that, he journeyed through several different game arcs. In Britain, he was King Arthur's childhood sweetheart. During the Fourth Holy Grail War, he found a girl who adored him... her name was Sajo Aika. After finally completing the game, Yuu Tōsaka was about to put the disc away for safekeeping when, one sunny afternoon, the Heroic Spirits he had captured in the past arrived.

Roger: Luo Ye is a complete monster!
