Ground Control to Psychoelectric Girl/Trivia
- The Danza: Hanazawa, a minor character on the shopping district baseball team, is voiced by Kana Hanazawa.
- Names to Know in Anime
- Miyu Irino: Makoto Niwa (Irino's first big Shaft role)
- Ai Nonaka: Meme Touwa (that may explain why Meme is one of the cutest anime moms to date)
- Emiri Katou: Ryuuko "Ryuushi" Mifune (Katou's big break from her nigh-real-life-breakdown-inducing casting as the infamous Kyubey)
- Yuka Iguchi: Yashiro Hoshimiya (It's Index! Except in a spacesuit! And claims she's an esper!)
- Kana Hanazawa: Hanazawa (heh... thank you, Maekawa)
- Shout-Out: Meme's dialogue is full of anime memes and references to video games. For example, she quotes the intro to MOTHER 1 multiple times when having dinner with Makoto. (Later, in Episode 6, it's shown that Erio has a Mr. Saturn plushie in her room, continuing the MOTHER references.)
- The ending has one for E.T. Erio ATTEMPTED to do the same. It... didn't work out, and is now the reason she wears that futon.
- Makoto saying he'll destroy Erio's illusions before deciding he's not Hot Blooded enough. He does it anyway.
- This in episode 5: Meme gives Makoto and Erio a map of how to get to a certain hair salon to get Erio's hair cut. Apparently Meme is a bit of a fan of Street Fighter.
- "Stop, stop, stop, stop! I'm a Makoto, too! Stop it! Time, stop!"
- "IIIIIIII KYAAAAAN'T FRYYYYYYYYYY!"
- "How much of that was you acting cold? "99.7% real, 0.3% acting." "What about me?" "About 5 Centimeters Per Second!"
- The last episode makes two more references to 5 Centimeters Per Second. The episode's title is "0.00000000198 Centimeters Per Second", and Makoto also says the words "One more time, one more chance", which is the title of the theme song of the aforementioned film. Another possible shout out is, perhaps, this series' protagonist sharing his first name with the director of 5 Centimeters Per Second, Makoto Shinkai.
- Erio's bizarre, pokemon-like noises whilst in the futon are a shout out to Full Metal Panic? Fumoffu.
- "Do you think I'd let a runaway who eats off fields in here?" Guess to whom this line is addressed to. Then think of a certain blue-haired character in a white nun's habit and remember how much of a glutton she is.
- Episode 11 references the Yiddish folk song "Donna donna" about a calf being taken to slaughter. Difficult to say where this one comes from, since it's appeared in numerous anime, including Revolutionary Girl Utena and Ghost in the Shell: SAC.
- Another one in Episode 11 when Makoto and Maekawa are playing a game on the television. It's Mario Kart with Different Colors.
- In episode 10, after Makoto and Yashiro jump into the pool, she says "Take this, Kamehamaha!"
- At the end of volume 3, Yashiro tries PK Starstorm on Makoto. The ensuing meteorite leaves quite a mark on him.
- The Wiki Rule: The Denpa Onna to Seishun Otoko Wiki
