Devil May Cry 4

Just replay the last lvl again, just this time dont let her get hurt >.> use streaks to push your enemies back, feel free to use dt as well, just keep pushing them away from her, dont worry about simply killing them. by the time you kill one they could easily come and hit her

Do the last lvl on an easier difficulty just dont let her get hit use dt and devil bringer for extra damage

Just use the blue rose and charge it up to first then fire to repel the scarecrows, use the devil arm when a scarecrow gets close to kyrie

Charge the Blue Rose while you attack the enemies. Make sure to do this on the easiest level. If you have trouble keeping them back, just use Streak (Up+Triangle). This will always knock them back. After your Blue Rose is charged to the max, shoot it, then charge it again. Repeat for 1'30.

Keep near Kyrie but not too close.When you saw an enemy near her pull it with the Devil Arm and kill any enemies around you
