Kousaka Yoshikage

Profile
One of the four Takeda generals. Compared to the other three, he is a very casual and easygoing person who rarely ever takes things very seriously. Despite this, he is an incredibly skilled ninja and scout, to the point where highly skilled ninja like Suzume and Inukai admire his abilities. He is killed along with Yamagata Masakage and Baba Shouen during the fall of Takeda house.

He can be captured and recruited during second games, after which it is revealed that he has struck up a friendly rivalry with Suzume over rock, paper, scissors, which he always beats her at and has known Inukai since he was a child, to the point of possibly being his father.

Trivia
He shares his level cap with fellow general Sanada Tourin at 55, making them both formidable warriors.

At 55, Yoshikage has the highest level cap of any ninja currently introduced in the Rance series, beating out Suzume by 6 levels.

All four of the Takeda generals have a game they enjoy playing and excel at. Yoshikage's is rock, paper, scissors.

Due to the fact that Suzume has never been able to defeat him at rock, paper, scissors and Inukai's assertion that she is a greater ninja than he is, Yoshikage may be the most skilled ninja in the series, though due to his canonical death this matters little.

He is most likely a reference to Kousaka Masanobu.
