bitch was tough. I'm a crazed Silent Hill fan... The only games I buy strategy guides for -- for collectors purpose.
from a boss guide:

Begin the first fight by equipping the Crowbar, if you missed it, the Fireaxe.
Scarlet's main attack is a swipe attack usually with her right hand. If you
remember from Sepulcher, he did the same thing. However Scarlet is a lot
faster and may take a few times to really anticipate her attack. Sidestep
dodge the attack, then quickly counterattack on her leg. Get a few hits off
as well before she tries to attack you again. Sometimes she throws you a
curveball and will go for a double swipe if she misses, you can tell this
is coming as she has a brief charge by holding her hand back before she does.
Again, practice (which may mean dying a few times as a result) will make
perfect to understand her attack pattern. You have two layers of her legs
to chip off before you can actually start knocking her over. Once all 2 parts
on both legs are broken, your attacks will now knock her to the ground. She
will not attack when she collapses so take this time to unleash charged
attacks on her arms. Once she rises up, repeat the process of dodging and
counterattacking on her legs until she falls again. Once both arms are
destroyed, she will change forms.

Now she will become a lot more agile and can even move across the ceiling
to surprise you. Have Alex keep his weapon readied so you can auto-target
Scarlet moving across the ceiling. When she is over you, keep rolling backward
to lessen the risk of her jumping right on top of you. Once she comes down
to the ground now you must prepare for all out offense. Equip the knife and
quickly get close to her, doing your knife combo as quickly as you can, meaning
do not charge any attacks. She may move positions after an attack or try to
counter you but keep following her and just lying on the knife combos
continuously. To put it bluntly: the knife messes her up. If done well, you
will not take any damage at all this form. The fight will end once you initiate
the fatality prompt when it appears.
