In the song アスノヨゾラ[哨戒班]{しょうかいはん} there is this lyric:
[未来]{みらい}を[少]{すこ}しでも[君]{きみ}といたいから[叫]{さけ}ぼう
〝[今日]{きょう}の[日]{ひ}をいつか[思]{おも}い[出]{だ}せ[未来]{みらい}の[僕]{ぼく}ら!〟
What role is を playing in the first line? There are no transitive verbs, so it doesn't look like it's marking [未来]{みらい} as the direct object of a verb, unlike in the second line where を clearly marks [今日]{きょう}の[日]{ひ} as the direct object of [思]{おも}い[出]{だ}す.
I'm aware that を has some other uses but I'm not familiar enough with them to see which one applies here.
