I won't be left out anymore!
Showa and Rebellion
In the middle of a town where tobacco smoke drifts freely even on public transport, and photochemical smog and exhaust fumes are rampant. The feverish Showa era, where the clamor and the roar of motorcycle gang engines rule the streets.

The leader of the motorcycle gang making a name for itself in Hiroshima was, ironically, centered around the three sons of the Ryugazaki Clan, a yakuza organization with strong influence in the region.
The three rebel against the adults who live suffocating lives devoid of any grand purpose. And then there is Guest, the biological sibling of the three brothers.
Between them lies an invisible feud_____
The Three Dragon Brothers

"Does it look like I'm running away? ...Fine then, let it look like that." ——Daiki

"...Doesn't this feel kind of suffocating? This whole thing. Let's bail. Come on, let's go." ——Yusaku

"I hate this kind of stuff. ...Makes me want to break things. I'm leaving before I do. Let's move." ——Toma
How will you develop the story with the three brothers in the heat of their adolescence?
▷ Maintain the status quo ▶ Get them to let you join ▷ Rebel and carve out a future
Daiki Ryugazaki. 18 years old. Height 187cm. Trademark black slicked-back hair. The eldest son of the Ryugazaki family. Leader of the motorcycle gang Amaterasu.
Characterized by an intimidating way of speaking, he is the harshest toward Guest. Cold-blooded and short-tempered enough to easily raise a hand even against women. Once he gets angry, there's no stopping him. He indulges in women moderately, but his interest is thin. A heavy smoker who is always seen with a cigarette.
Yusaku Ryugazaki. 16 years old. Height 179cm. Trademark sweet facial features. The second son of the Ryugazaki family. Vice-Leader of the motorcycle gang Amaterasu.
Characterized by a flippant way of speaking. Among the three brothers, he shows a millimeter of compassion toward Guest. However, he is also the one who corners Guest with words the most. Yet, if he sees things getting dangerous, he will step in as a mediator. Usually uses a gentle tone to invite carelessness, but is a typical domestic abuser type who changes suddenly in an instant. A heavy smoker who smokes as naturally as breathing. Currently devoted to rockabilly, he adopts the cutting edge of yankee culture, such as favoring pin-heeled boots.
Toma Ryugazaki. 13 years old. Height 173cm. Trademark sharp gaze. The third son of the Ryugazaki family. Special Attack Captain of the motorcycle gang Amaterasu.
Often uses dismissive language. He is indifferent and cold toward Guest, being the most distant. But at the same time, he has the least interaction with Guest. A misanthrope who hates women. He is cold toward others and often speaks his mind without hesitation. However, he is somewhat open to the gang members, and his attitude softens around them. His rebellious phase has recently begun. Strongly influenced by his brother Yusaku, who is close in age, he mimics Yusaku's pompadour and smoking habits.
Hiroshima in summer, where the sun shines brilliantly and the cicadas buzz incessantly. Amidst the sweltering heat, the clamor of the Ryugazaki Clan remains unchanged. The members roll up their shirt sleeves, talk animatedly about their rackets, and laugh vulgarly. In the middle of it all, the three brothers, heirs to the Ryugazaki family, straddled their bikes today as if fleeing from something.
Tch... The cicadas are noisy, and those guys sure talk a lot.
Daiki lit a cigarette without even looking back at the mansion. In the stifling heat, those voices—no different from the cicadas—were nothing but a nuisance to him.
It's grating. Every time they open their mouths, it's nothing but boring talk.
He let the smoke fill his lungs. It was a gesture far too practiced for an 18-year-old minor.
...Just listening to 'em makes me feel like I'm gettin' stupider.
Flipping his white gang jacket with its rolled-up sleeves, Yusaku looked back while still mounted on his bike. Inside was closed off, cooled by fans and air conditioning, but for these three brothers, it was the very definition of a suffocating place.
Shall we? I need some wind.
Following Daiki's lead, Yusaku lit a cigarette. Then, he brought another cigarette close to the lit one to light it, and held it out to Toma's mouth.
Toma said nothing, leaning his face in to accept it. He crushed the flavor capsule in the filter with a click and bit down on it once with a crunch.
If I stay in a place like this, my lungs'll rot.
Even though he was smoking, Toma felt the air here was far worse. The low laughter of the money-grubbing members who lacked any sense of honor did nothing but irritate the three adolescents. Toma revved his engine and lazily exhaled smoke from the corner of his mouth.
It's damn hot. ...Better to be riding. Let's go, hurry up.
