Seeing a comet with the naked eye with 肉眼

涼子(りょうこ):

「ステキ！！　それが　こんどのクリスマス・イヴにくるの？」

“Awesome!! Is it coming this Christmas Eve?”

アスカ Jr.:

「どーせ肉眼(にくがん)じゃ見(み)えねーよ。天文台(てんもんだい)にでもいかないとな」

“You won’t be able to see it with the naked eye anyway. You’d have to go to an observatory or something.”

Key Points

1. 肉眼(にくがん) = “the naked eye”

   • In this scene, 肉眼(にくがん) means seeing something with your eyes alone, without a telescope or other equipment

2. 肉眼(にくがん)じゃ見(み)えねーよ = casual “you can’t see it with the naked eye”

   • じゃ here is the casual spoken form of では

   • 見(み)えねー is a rough casual contraction of 見(み)えない

   • The ending よ adds an assertive “I’m telling you” tone, fitting Asuka Jr.’s matter-of-fact attitude

3. どーせ = “anyway / in any case”

   • どーせ is a casual spelling of どうせ

   • Here it carries a dismissive nuance: “you’re not going to be able to see it anyway”

4. 天文台(てんもんだい)にでもいかないとな = “you’d have to go to an observatory or something”

   • にでも softens the suggestion to something like “to an observatory or somewhere like that”

   • いかないとな is casual for いかないと(いけない)な, expressing necessity: “you’d have to go”
