The background art of the food truck park is packed with visual references to other Lovestruck games. Comet from Starship Promise appears as a mascot on one of the trucks, and among the background characters are figures resembling Nova, Orion, and SP's heroine, Altea Bellerose and the heroine from Love & Legends, Arthur Singh and the heroine from Castaway! Love's Adventure, and a blond man who could possibly be meant to look like Chimera from Astoria: Fate's Kiss.
In Andi's second season, she and the heroine watch a movie about werewolves in Indiana and Andi cheers at the vampire huntress villain character, referencing Havenfall Is for Lovers and one of its characters, Vanessa.
Andi's fourth season is full of references to other Voltage stories. First, the mansion MC and Andi stay at in Los Angeles is from Gangsters in Love. Second, while lounging by the pool, MC reads a trashy gossip magazine and discovers that Jonas Quinton was arrested in backwater Indiana, a reference to Razi's route in Havenfall Is for Lovers. Third, when MC and Andi watch a fantasy anime and discuss three characters in it, they're Altea, Helena, and Iseul. And fourth, after the anime, they check the recently watched list and find a documentary on Mothman, which leads to a discussion of seeking out the birthplace of the Jersey Devil.
A scene in Duke season 4 references John Mulaney's "Salt and Pepper Diner" routine. Monarch reveals her ringtone for Andi is "What's New, Pussycat?" (at which Andi boos) and Bat remarks, "You know, I bet I could hack your phone so that every so often it plays ‘It's Not Unusual’, instead..."
A couple times in Renzei season 3, Bat sings, "Meet the new __, same as the old __," a reference to The Who's "Won't Get Fooled Again".
In Duke season 5, Bat unleashes "pocket sand" (actually a burst of light) against some Optimus guards.
In a heart scene in Duke's fifth season, Bat boasts about being great at Typing of the Damned. Monarch comments that that sounds like it would be terrifying to witness — "We're talking beautiful and terrible as the dawn."
In Duke season 5, Bat is tempted to make a Max Headroom joke when setting up the broadcast hijacking.
During a game of I Never in Duke's fifth season, Renzei calls Bat "Lite Brite".
After seeing a weakened Scarlet in Lorelei's fourth season, Bat remarks, "Yikes. I need an old priest and a young priest," referencing Austin Powers: The Spy Who Shagged Me, which itself was referencing The Exorcist.
