Urashima Jirou

The famous younger brother of Urashima Taro.
Using the treasure brought back from Ryuuguu as political funds, he to climb to the top and become the governor of Kagawa prefecture.
Hobbies include picking up girls, gastronomy, fishing, sightseeing, and wearing shiny things.
He is a nouveau riche spender, but he is generous to everyone, so nobody can hate him.
Since he has been in Ryuuguu for a long time, he isn't familiar with the geography of Shikoku, despite being the governor of Kagawa prefecture.
He doubts that he can't even find Kagawa prefecture on a Japanese map.
