Might be because i am not so good but i just cant plain beat her spell cards on normal difficulty and she is like the hardest stage 6 boss for me, only kanako getting close, any tips on how to deal with utsuho?
Bomb everything. This is SA, so you can bombspam quite a lot.
More in detail :
First nonspell is trivial, just stay at the bottom under her and move a bit if needed.
First spell is really hard. General strategy (in normal) is to alternate between middle-(left/right)-middle--left/right)... when she shoots the big suns at you. Don't be afraid to use one or two bombs here.
Second nonspell : dodge the blue lines, then slowly stream the big bubbles, starting from the bottom (try to stay under her the more possible so it doesn't take ages).
Second spell : no real trick here, the hardest part is to read the small bullets hidden by the big suns. Bomb when needed.
Third nonspell : trivial, there are some huge gaps, stay under her.
Third spell : there is some kind of safespot. You can stay on the horizontal line where the two circles of suns intersect, so you only have to dodge the small bullets, moving horizontal-only.
Fourth non : same as second, a bit easier.
Fourth spell : no real trick either. I usually try to stay in the middle on the screen and micrododge horizontal-only, but there are lots of ways to do it. Bomb when needed.
Final spell : read the barrages of yellow bullets, get used to the gravity change, don't get clipped.
Go watch any perfect stage 6 replay for more details, there are a few ones on youtube (it's on lunatic because people are crazy, but still).
Again, if you're going for a first 1cc, don't hesitate to bomb a lot. Continue-spam stage 6 once you get there, it's painful but you'll learn to plan everything. You can clear the stage, starting with 2 lives, while bombing all the hard stuff.
