お空とミスティアの服は偶然ビキニっぽいなにかにアレンジしたので
鳥たちみんなビキニスタイルで行こうと決めた

昨日寝る前に

はたては引きこもりだからあんな服着る勇気がないみたい

Coincidentally, my version of Okuu and Mystia's clothes look like bikinis, so I decided to have the birds go for the bikini style.

Yesterday, before sleeping

Hatate is a shut-in, so it looks like she doesn't have the courage to wear that kind of clothes.
