Regen is a blonde, pompadour-wearing apprentice cook who idolizes Sanji. He turns up only in the promotional Sanji's Pirates Restaurant 2022, where he waits on a noisy crowd of pirate diners and gets spooked by the rougher patrons.
Short in stature and pale of skin, this young man shapes his blonde hair into a pompadour, with brown brows set beneath it. For clothing he favors a relaxed mix: an orange hoodie cut with short sleeves, loose overalls of a tan shade, and sneakers in black whose soles are colored white.
Diners are met with friendliness and an open welcome from Regen, though a streak of mischief sits behind the smile. The pirates drifting through the eatery, Law among them, frighten him with little effort. Counting himself a fan of Sanji is something he takes pride in.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...
Not long before the concert Uta would give on Elegia, the crew of Straw Hats put in at an island, and there Sanji set up a short-lived restaurant, taking Regen on to help run it. Working the floor, Regen became sure that the markings on Law's hat were wearing away. Raising the point with Law only irritated the pirate, who scared him off, so Regen came back holding a chocolate pen a customer had handed him and presented a plate proposing to ink the spots back in with chocolate, which earned a second irritated dismissal from Law. With Luffy, Zoro, Law, and Kid wrecking the mood through endless arguing, Regen floated the idea of a near-impossible legendary ingredient, which sent the three captains off competing to find the finest one within reach. Working as a cook apprentice, he is taken to hold at least some ability at the stove.

Regen appears in Sanji's Pirates Restaurant 2022, where he waits on a noisy crowd of pirate diners, including Trafalgar Law, Luffy, Zoro, and Kid.
Regen is short and pale skinned with blonde hair styled into a pompadour and brown eyebrows, and he wears an orange short sleeved hoodie, loose tan overalls, and black sneakers with white soles.
Regen is friendly and welcoming toward customers but has a mischievous streak, and he is easily frightened by the rougher pirate patrons, especially Law.
Working the restaurant floor, Regen became convinced the markings on Law's hat were fading, and when Law brushed him off he offered to redraw them with a chocolate pen, which only irritated Law again; he also sparked a rivalry among Luffy, Zoro, Law, and Kid by mentioning a near impossible legendary ingredient.
