This boss will attack you in 3 ways:

- Throwing a vertical fireball to the ground making spikes come from the floor - To avoid, stay on top of any umbrella;
- Making it rain over you - To avoid, go under a umbrella quickly after boss start glowing.
while jumping over umbrellas or special moves 
- Zangetsu's whip while jumping or Miriam's daggers from the floor.As a reminder, it's specially important to avoid the rain, as it seems to be the strongest attack.
At last, after defeating the boss she'll throw one final blow on you. To have better chances of avoiding it, stay as far right as you can.

Story related and cannot be missed.
You must beat the sixth stage, Tragedy of Slaughter.
Shortly after the beginning of the stage, you will find the stages upgrade item, a Gauntlet. Zengatsu can reach it if you have Soul Arts and no allies.
The boss of this stage is an early backer revealed boss, Bloodless. She summons umbrellas for you to use as platforms. She floats at the top and will snicker, wait a few seconds, and then drop an attack that falls to the floor and makes blood spikes along the entire floor. She will snicker again, wait a few seconds, then make it rain blood where you have to hide under the umbrella’s to avoid damage.
Her desperation move turns her into a tornado of blood that flows from left to right twice, avoided by moving to the very edge of the screen, then on the third pass her head appears inside the tornado which can be attacked creating an opening for you to jump through and avoid the damage.
