Kiyomasa Katō

Kiyomasa Kato (加藤 清正) is loyal general of the Toyotomi clan and one of the Seven Spears of Shizugatake. He is one of the many generals who joins the Eastern Army prior to Sekigahara.

Samurai Warriors
In Samurai Warriors 2, Kiyomasa is always seen alongside Masanori Fukushima. They act as Nene's closest "children" and are very loyal to her. They address her as "Lady Nene" at all times. However, he can't stand Mitsunari and often berates him. When Sekigahara takes place, he is one of the generals in the Eastern Army. During Nene's dream stage, he apologizes for his rash behavior.

He's currently speculated to be one of the new characters in Samurai Warriors 3.

Kessen
Kiyomasa is a general who appears with Josui in Kessen. He's Masanori's childhood friend and won't fight him if they're on opposing sides. He's usually mute in the game's cutscenes but will talk if he meets Masanori in battle. He leads a sturdy cavalry and is one of the faster units in the game. Depending on the actions of the player, both of them can fight together on the field.

Kiyomasa can be recruited into Nobunaga's army in Kessen III. If Hideyoshi's unit survives the battle at Anegawa, he will appear. He has a high cavalry proficiency and can serve as a good spear unit.

Saihai no Yukue
He returns as a minor general for the Eastern Army in Saihai no Yukue. His hatred of Mitsunari is downplayed.
