All I've heard is that they chose Ayaka out of Reina, Reika, Erika, and Ayaka (lol)
I don't know...
I don't know!!
I wonder if they wanted to raise me to be cheerful~.

Though I don't really know, since it's a bit Showa-like the "莉" (Ri) gave a sense of girlishness. Or something like that...
I heard that they gave it to me since the "moe" of 萌衣 has a meaning of budding plants, and so with that sense of vigor they wanted to raise me to always be energetic and healthy.
I hear they named me "Momona" since in Hawaiian it means "sweet", and they hoped to raise me to be a sweet girl.
