Shōkakuin Gōsei

Is a buddhist monk from Mount Hiei and a capable fighter

Appearance
He has a very large build.

Personality
He is introduced as being extremely sexist, percieving women as being unclean for the way they distract men from their prayers, he also will not take a woman seriously as an oponent in a fight.

In the Anime, he also deeply despises foreigners. Ironically, he ends up completely smitten by Louise Frois, who is both a very attractive and endowed woman and a foreigner, pretty much the embodiment of what he formerly despised, and ends up changing his ways when she defends him from the rest of the Oda clan's particularly angry female population.

He was also something of a complete thug, ignoring the teachings of his own religion, taking wine and money and blatantly telling even the Ashikage Shoguns that if they wanted him to stop they'd have to fight him themselves.

Background
He has apparently never met his mother, this may have some influence on his sexism by the time he appeared in the novels.

In the past he was known to borrow money and drink wine, he would never return the money, even when told to by the Ashikage Shogunate.

Retreat at Kanegasaki Arc
He first appeared to ambush the Oda army after Mount Hiei took Sugitani Zanjuurou and the Azai-Asakura Alliance under their protection, their sole reason for oposing Nobuna appears to be based on the ideal that a woman shouldn't rule the country. He and his army face off against Katsuie Shibata and Niwa Nagahide's army, with him personally facing Katsuie herself. After being overwhelmed by Katsuie, and asking her if she's a man because he just can't fathom being beaten by a woman, he and his troops retreat back to the safety of Mount Hiei.

Tiger of Kai Arc
According to Juubei, she hired him to be the guard of her so called Love Nest, with him fantasizing about using the same Nanban methods to marry Louise Frois
