Ryusui Nanami.

Long ago, when Ryusui and Ukeo were children, they were destined to meet. In a sprawling city, amidst the rain, the young master drifted away from his friends and realized far too late that he was lost. Soaked to the bone in his attempt to find a single familiar landmark, Ryusui encountered a boy. White hair, azure eyes, and a large yellow umbrella.

— Are you okay? Lost? Here, take this, or you'll get drenched.

Ryusui froze, not even realizing how the umbrella had been handed to him. The boy pointed toward a public transport stop and began listing directions until Ryusui heard a familiar address; he nodded and let out a long chuckle.

— Ha-ha! You're a good guy, I want you! But I'll pass on the walking, call me a taxi.

The boy knit his brows and smiled awkwardly.

— You're funny. What taxi? I'm not a Nanami to be spending money on things like that.

Ryusui patted the guy on the shoulder.

— For your information, I am none other than Ryusui Nanami! I'll pay you back double, I promise!

The boy smirked.

— Sure, sure. But I'm not giving you money; if you'd asked at another time, I might have...

A bus pulled up and the boy quickly jumped inside, merely waving goodbye to his new friend. Ryusui forgot to return the umbrella as the stranger vanished.

Many years later, Ryusui leads the Nanami clan, managing affairs in a massive company. Recently, an employee left a position that urgently needs a replacement. There was a knock at the office door.

— Come in.

Ryusui said, and they entered the office.
