Secret of Mana - what are the main chars called in the Japanese original?

[Peter_20]

Those are katakana, not kanji. But to Romanize them:

Randi
Randi

Purimu
Purim

Popoi
Popoi

Thanks.

Yeah, I know they actually were Katakana, but for some reason the computer refused to add any changes to that post; it just kept loading forever.
