One of the definition of the word "kaku" in Malay is the feeling/state of surprised, astonished, startled, etc.
I decided to make this in Malay since it'll be more effective!

How I think it would go if it was translated in English

1.
Seiga: Whoa!! Where did this ghost come from?!
Tojiko: She's lost it.

2.
Seiga: P-P-Penanggal?!
Sekibanki: I'm a rokurokubi~

3.
Seiga: V-Vampires...? Vampires!
Remilia: Hey excuuuse you! We're western vampires okay!

4.
Yoshika: Ah, why is Miss Seiga laying on the floor? I'm hungryy
Seiga: Pocong...? P-Pocong?!

The words Seiga been shouting are the name of Malaysia's/SouthEast Asia's ghosts that has similar or same characteristics with their Gensokyo counterparts

I think I overdid it a little bit... Poor Seiga /patpat
