Yes, I read that Chara means ''joy'', it also means ''guardian'' owo

And Frisk name means ''healthy, fresh, joy, it has meaning in english, swedish, danish and norwegian as well

and of course~



Referring to that I didn't take it that way but now that you mentioned it, yeah, it can be! Also, it means that either Frisk consider Asriel a star -since he has those attacks on his battle- or that Frisk will become a star once they die forever
