Yoshimoto Imagawa - 4th Weapon | Samurai Warriors 2: Xtreme Legends (4k, 60fps)
Super easy, which is good as he's the worst character in the game by an absolute landslide, as his moveset is complete trash (His R1+ Square Special takes too long to execute that enemies will manage to get up before you can use it)
Stage: Battle of Kawanakajima ( Stage)
Requirements: Without Kansuke Yamamoto being defeated, defeat Takahiro Hojo, Sadanaga Sanbonji and Kagetuna Naoe (They all appear as Ambush Troops in the fog) within 3 minutes of them appearing.
Weapon Location: Very top of the map in the center of the pathway.
Tips: Just play the stage as you normally would, but when Kansuke Yamamoto goes to the south east garrison and gets "Ambushed" prioritize saving him and defeating the 3 officers that appear, head out of the foggy area to see where they are in relation to you by going back in as the map disappears.
