Nabeshin mentions stands when he is fighting the hanging balls dude at the beginning of the first episode. This is reference to the manga/anime Jojo's Bizarre Adventures.
In Episode 1 during the fight between Nabeshin and Alien 1, Alien 1 summons a spiritual being resembling the "Stands" of Jojo's Bizarre Adventure. Nabeshin comments on this, saying, "Looks kind of 'Stand'ish to me."
