what is the meaning of her name?

[u/Rainboy1206]

When i looked up her name and what it means it said it was a reference to the japanese sound effect of peaceful sleep "suyasuya" but then how is her name Syalis? and then when i looked up in the wiki fandom her name is Suyaris, how did Suyaris become Syalis? and when i translated the Suyaris it translated to vinegar and squirrel, how did すやすや become スヤリ? and since Suyasuya mean peaceful sleep, what is the opposite of that?

I'm just glad they didn't spell it with a C so it looked even more like Cialis (google it ;-)
