I don't know if this is exactly worth noting, but doing different variations of hazama's tk input may or may not help with connecting [5c > 2c > 214d (b) > 3c > mizuchi] on smaller character's falling hitboxes. Like makoto, noel, etc.
So something like Corner : 5b > 3c > 236d > 6c > dash 5c > 2c > 9214b > dash 5c > 2c > 7214b > 5c > 2c > 7214b > 5c > 2c > 214d (b) > 3c > mizuchi.
