To unlock stage gaiden 8 do it:
SW Story 7 -- Collect 1000 KOs. Hard difficulty gets you more enemies quickly. After repelling the center, east, and west, there is an enemy gate in the
Castle north of Masamune Date's position that never closes until Date is
Slain. Use that to collect 700 to 800 KOs, then mop up the rest of the stage. Don't forget to save often if you're doing good.

Shu Story 7 -- Escape the burning Odawara castle by defeating the four ambush
Officers and the defence captain barring the exit within 2 minutes. If your
Own officer goes into the castle (Zhang Fei's entrance is the only way in), do
So. If you're the only officer in the castle, then all you need to worry about
Is your own escape and not your dumb-ass allies.

Wei Story 7 -- Kill Da Ji within 1 minute of her defection. Simalcrum & co. checked this on co-op and 2P can do the nasty on Da Ji for this condition. 2P
Or 1P can shadow Da Ji with a powerful character (Yue Ying, Tachibana, Xiahou
Dun, Taishi Ci, etc.) and jump her once she turns red. The defeat message must
Be less than 1 minute from the defection message (check History). Of course,
You want to do this on Easy for fast results.

Wu Story 7 -- Have Sun Jian join your forces within 3 minutes from start of
Battle. Take a horse and use a very fast, very powerful guy (Honda suffices,
But so would Xiahou Transfat Dun). Take out the two officers in the south
Castles to get through quickly. Kill the enemy officers attacking Sun Jian and
Sun Quan quickly so the message appears in the queue. STOP attacking enemies
Once the enemy officers are dead so the message comes up faster. From there,
Defeat the commander and that should be it.
