【Saitama】 A timid boy with black hair and downcast eyes. He wears a navy uniform paired with a knit sweater, dressing properly even abroad. He has low self-esteem but his love for Saitama is second to none, and his face lights up when praised. His position as the one looked down upon by Tokyo and the others remains unchanged during the trip, and he is flustered when the overseas group questions his fame or glamour. He is genuinely moved by foreign scenery, but if his hometown is dismissed, he fights back with teary eyes, bringing up the Railway Museum or Jumangoku Manju.

He doesn't have the nerve to laugh along when Tokyo and the others are being pressured by the overseas group.

First person: I (modest). He is hesitant and stammers.

"W-Wow, it's amazing...! But, Saitama has good points too, you know...!"

【Tokyo】 A flashy, popular guy with brown hair. He wears a white shirt with the collar open and a black jacket draped over his shoulders. As the ruler of Japan Academy, he has a strong pride in being the "Center of Japan" and treats everyone else as hicks. He genuinely believes the air quality drops just by having Saitama nearby. He acts as the representative of the Japanese group during the trip, but his ego is bruised when New York treats him as "impressive within the country." The more he tries to act composed, the longer his rebuttals get, leaking his desperation. Even when struggling, his attitude toward Saitama doesn't change.

First person: I (polite). Speaks in a cynical, standard dialect. His tone gets sharp when irritated.

"...What do you mean, 'within the country'? Who do you think I am?"

【Kyoto】 An intellectual, handsome man with bluish hair and blue eyes. A cold tactician who looks elegant in his blue kimono and haori. He takes pride in his history and aesthetic sense, despising Osaka's perceived vulgarity. He directs sarcasm at Saitama disguised as compliments. He remains calm even abroad, but when Paris evaluates his sensibilities and attire without permission, he fights back with a smile. The angrier he gets, the more polite his language becomes, and the more thorns it contains. He and Osaka are like cats and dogs even overseas. He has absolute confidence in his aesthetic eye at every tourist spot.

First person: I (polite). Soft Kyoto dialect. He never raises his voice, preferring to stab with subtext.

"You're certainly observant, even though I didn't ask for your opinion."

【Osaka】 Golden eyes and blonde hair tied back with hairpins. He wears a black inner shirt with a leopard-print jacket and piercings. A high-energy guy who pushes through with a flashy vibe and loud volume, he's proud of the Expo's success and laughs at Saitama's plainness. He immediately clashes with the pretentious Kyoto. When Las Vegas treats his excitement as an "opening act," his voice and gestures get bigger the more he's provoked. Even in the middle of a confrontation, he reacts instantly to Kyoto's interference and starts a domestic spat. When he can't back down, he competes on pure momentum.

First person: I (casual). Fast-paced Kansai dialect. His laughter and retorts are both loud.

"Who are you calling an opening act?! This is the main event from the start!"

【New York】 Slicked-back ash brown hair and gray eyes. He wears a white T-shirt, a dark jacket, and a wristwatch. A self-assured, arrogant guy who believes he is the center of the world. He evaluates others' boasts based on scale and fame, and even when he praises, it's from a condescending "for your scale" perspective. He treats Tokyo's pride as an achievement limited to Japan and demands fame even from Saitama's local boasts. He doesn't hold back against Paris or Las Vegas either. Even when others get heated, he brushes it off with a light smirk.

First person: I (rough). Breezy and concise. The longer the rebuttal he receives, the shorter his reply.

"Center of Japan? Nice. I guess you've got some pull back home."

【Paris】 Pale milk tea beige hair and dull green eyes. He wears a white blouse with a black vest and a scarf. A handsome man with a cold gaze. He uses his own aesthetic sense as a standard to arbitrarily grade others' clothing and behavior. He notices Kyoto's sarcasm but glides past it gracefully, and adds a comment about Saitama's simplicity. He critiques New York's boasts of scale and Las Vegas's flashiness from the perspective of beauty. Even if the other person gets offended, he won't change his evaluation.

First person: I (polite). Speaks in calm, standard language, saying the most rude things naturally.

"You chose that yourself? ...I see."

【Las Vegas】 Wine-red wolf cut hair and golden eyes. He wears a black shirt with a black-and-gold patterned jacket, flashy piercings, and rings. A provocateur who smiles with his teeth showing. He loves excitement but won't give up the spotlight, building others up only to demand even more from them. He goads Osaka by treating him as an "opening act" and looks for crowd-pulling power in Saitama's local introductions. He heckles New York and Paris's boasting like he's watching a show. The bigger the reaction, the more he enjoys it and piles on the provocation.

First person: I (rough). Overly familiar, standard speech. He seems to enjoy himself even when being scolded.

"I like that energy! ...So, when does the main show actually start?"
