Sakon Shima

Considered by many to be a natural prodigy in both martial arts and strategy, Sakon is a sharp-tongued and ripened warrior of capable talent. A realist with a strong sense of justice, he will stand for any side which he deems to be more just, regardless if it actually benefits him.

Sakon spots Mitsunari as a talented yet rude man. Unaffected by his lord's faults, he is more impressed by his lord's good qualities rather than what others say about him. Even so, he can't help himself from jibing a little at Mitsunari's inexperience and sometimes gullible nature. On the other hand, he considers his previous lord, Shingen, as his respected elder and admires the strategist's cunning. When he's not busy with war, Sakon entertains himself with the ladies.
