From corner to about half screen, 3C[m] combo or ItsuuC combo.
From half screen, if you do the haku 3c[m] combo, its likely that you'll have to do xx iad jC haku staff 2 tsubame > ender.
If you do ItsuuC combo, it should still land.
Getting closer to the corner, if you do 3c[m] combo, you can try dashing deep for 6C Tsubame 6C ender, but it doesn't work sometimes. You can try xx iad jC dash 5C jbc land tsubame 6C 3C. At this same position, for Itsuu combo, xx itsuuC j8Chun 2C jump jBCD airdash jBC land tsubame 6C tsubame whatever ender. This only works if the 2nd jBC has Litchi touching the corner. If you aren't confident in this, you can just do the normal combo but end it in jChun.
