Korenobu Yufu

Korenobu Yufu is a retainer of the Tachibana and leader of the clan's Four Guardian Kings. Having stepped down as family head to serve under Dōsetsu, he fought in over 65 battles and sided with Muneshige even after the Tachibana had been stripped of their rank.

Role in Games
Korenobu Yufu is often seen fighting alongside the Tachibana at Kyūshū and Ishigakibaru. In the third game, his defeat is necessary to break down the Tachibana's vanguard. Motonari's requires the player to lure him out of the southern garrison instead. The expansion has him serve as an obstacle for Kotarō to face at Odawara.

His earliest appearance in the fourth game is at Shimanto River. He and Shigeyuki Ono serve as sentinels for Tachibana Castle, forcing players to take them out for control.

Historical Information
Once a servant of the Ōtomo clan, Yufu Korenobu held dominion over Bungo province before serving the Tachibana. Together with Shigeyuki Ono, they were called the Twin Walls of the Tachibana. In 1587, Korenobu helped overthrow the Higo army by breaking their will to fight. After the Battle of Sekigahara, he left for Edo and remained loyal to Muneshige until his death.
