How do Du pronounce all the girls' names?

bubbles: ba-bulls
blossom: bla-sum
buttercup: butter-cup

I believe you're talking about their Japanese names when they're not transformed. Here they are:

Momoko Akatsutsumi: Moe-Moe-Koe Ah-Cot-Suht-Sue-Me

Miyako Gotokuji: Me-Yah-Koe Go-Toe-Kooh-Gee

Kaoru Matsubara: Kah-Rue Maht-Sue-Bahrah


Blossom is Momoko, Bubbles is Miyako, and Buttercup is Kaoru.

Blossom is momoko and it's pronounced ma-mo-ku
Bubbles is Miyako it's pronounced My-I-ko
And buttercup is Kaoru and it's pronounced Ka-ru

Momoko: Ma-MO-ko
Miyako:Me-YEAH-ko
Karou:Car-OO
