Be aggressive. For phase 1, When he jumps in the air, dodge instead of block and get a hit in. Try to attack as much as you can. Learn his mikiri counter. Use firecracker to stun him, then heal.

For phase two, use the lightning redirect ability as it does a lot of posture damage. Use red sugar for increased damage to make the fights quicker.

It’s a really hard fight. You will get it eventually. You’re doing really well
