Can my Honkai Star Rail Hardcore account beat Kafka? 

In this episode we take on the first Half of the Xianzhou Loufu and fight Kafka, but can I come out unscathed?
Rules are:
1. If a character dies, they must leave the party permanently.
2. No over-leveling.
3. Account is F2P.
4. No retreating.*
5. If Trailblazer dies, the account DIES.
6. I must fight all available formidable fights before the next story boss.
Regarding rule 4s asterisk, I'm allowed to enter key boss fights to check their level because sometimes that information isn't reliable online.
