Question

for ki theres two ways to write it and for sa theres also two ways.

Answer 1

we learned to write like

ki -> 4 strokes

sa -> 3 strokes

not connected writing at school.

connected one are just different font i guess.

im not sure but there're tons of different different font in japanese as well. english "a" is different from hand writing right? same as 'sa' and 'ki'.

i was dtp designer. saw lots of font to design. so this is just a my opinion :)

Answer 2

There isn't. Do you mean hiragana and katakana? In hiragana, there is definitely only one way to write ki and sa.
