Fan Club of Shun Akiyama, Lifeline of Kamurocho!

Shun Akiyama is an independent moneylender who runs a lending company called Sky Finance, based in the Kamurocho district of Tokyo. Once a successful bank employee, he became indirectly involved in a 10 billion yen theft incident and then lost his job because of it, found himself at the rock bottom, forced to live and wander on the streets of Kamuro as a homeless man, until the money rain caused by Millennium Tower bombing in 2005, which gave Akiyama a new opportunity for a happy life and successful business. The principle of his company is to give money to people with no interest, no collateral and no limit, but with one thing — a person must prove their desire, passion and goodwill by passing a test that basically shows Akiyama what kind of person they are and if they need this money at all. Shun have a soft spot for the people who's able to dream selfless, for example — about something greater than one's life, driven by passion and benevolence.
Akiyama is a very kind person, always willing to help others around himself, especially if those people are homeless or on the edge, always remembering how he was abandoned and ended up helpless on the streets years ago. Knowing that he can't save every single person, he believes that Kamurocho needs a hero of justice that could save everyone in need, even those who don't need a loan, make the city and its streets safe for everyone — and he saw such a hero in a legendary Kazuma Kiryu, who went missing at that time, which made him try to find a new city legend.
But in terms of his other personality traits, Akiyama is a lackadaisical person and a slacker who doesn't always take his workdays seriously, often spending huge amounts of time sleeping on the couch and reading magazines, much to the chagrin of his secretary and manager Hana-chan, especially when he forgets about his own responsibilities which creates very funny situations.
Despite the mask of non-seriousness that he wears, one can assume that he is a very sensitive person and easily driven to anger by injustice and unfair treatment of other people.
Also some random street encounters call Akiyama a pretty boy with a pretty face, I find it very funny.

As much as I don't like AI stuff, this Koi no Disco Queen cover by BalkN goes so hard.
