Quest Mode Translation
Use the suicide/desperation attack (CIRCLE attack) more than 30 times. The 
needed limit is less on earlier levels than later levels, but use the attack this 
many times to be sure. 

Stage 1 at least 15 times 
Stage 2 at least 15 times 
Stage 3 at least 20 times 
Stage 4 at least 20 times 
Stage 5 at least 30 times 
Stage 6 at least 30 times 

Clear all the enemies from each room or hallway you come across until no more 
enemies respawn. The enemy count also includes the rooms you re-enter by 
accident. 

Enter "bloody mode" at lteast eight times in a given stage. Some stages have a 
higher requisite limit than others. 

Stage 1 at least 4 times 
Stage 2 at least 6 times 
Stage 3 at least 8 times 
Stage 4 at least 8 times 
Stage 5 at least 4 times 
Stage 6 at least 4 times 

Perform a 25-hit "just frame" combination in a stage (it may have to connect with 
an enemy to count). Notice sometimes the sword has a wavy effect when 
attacking -- you pressed the SQUARE key at just the right frame to do extra 
damage (or 'Cool Attack'). The timing of the button press is delayed slightly on hits 
3, 6, and 9. The combination statistic must be at maximum for this challenge to be 
possible. 

Get a continuous set of combo hits/kills in a preset period. The period differs 
depending on the stage. 

Stage 1 about 13 seconds 
Stage 2 about 15 seconds 
Stage 3 about 17 seconds 
Stage 4 about 19 seconds 
Stage 5 about 21 seconds 
Stage 6 about 23 seconds 

Kill the boss of the stage under a preset period. This varies depending on the 
stage. The timer only starts when you first face the boss. 

Stage 1 under 20 seconds 
Stage 2 under 30 seconds 
Stage 3 under 60 seconds 
Stage 4 under 35 seconds 
Stage 5 under 40 seconds 
Stage 6 under 45 seconds 

Clear a stage without being struck by an enemy or enemy attack. Note O-Ane-
Chan may still lose life from "bloody mode" or the desperation attack and fulfill 
this challenge. 

Clear a stage while still in "bloody mode". Very easy if you anticipate fighting the 
boss. 

Clear a stage with the lifebar flashing in warning. Very difficult if you do not have 
the invincibility gem against some bosses. Planning ahead helps. 

Clear a stage with a 100% bloody sword. Very easy if you couple it with "bloody 
mode".
