- Late Export for You: The manga took nearly ten years to get an English translation.
- The Merch: The anime had a minimal amount mostly consisting of hand-bags.
- Name's the Same: Shuuichi, Makoto, and Yoshino are also names of characters in Minami-ke, and the other Makoto is a crossdresser who goes by the name Mako-chan. However, unless it's Minami-ke doing the shouting, this could not be a Shout-Out since Minami-Ke started two years later than Wandering Son.
- No Export for You:
- The anime hasn't officially been released outside of Japan physically. It's only available on Crunchyroll.
- The English translation of the manga didn't finish the entire run.
- What Could Have Been: The manga was going to be about a high school aged trans boy, but Shimura decided a preteen trans girl would make for a more interesting plot and have more issues. Takatsuki was created as the Deuteragonist, albeit a lot younger than expected.
- Unintentional Period Piece:
- The manga began in the early 2000s and ended in the 2010s. It ran more-or-less in real time and shows the changing views on trans kids in Japan. Takatsuki and Nitori aren't pariahs but their parents and teachers don't know what to do about their gender issues. If the manga had begun in the mid-to-late 2010s, this might have been different, as more teens and preteens in Japan are coming out as trans and presenting as their gender at school.
- There are elements of 2000s and 2010s technology sprinkled about, such as Takatsuki and a few other characters owning Playstation 2's. In an early chapter, Nitori and Mako record their voices on a tape recorder; this is given a Call-Back when Nitori listens to the tape as a high schooler. The anime changed it to the two recording on smartphones.
- The Wiki Rule: Hourou Musuko Wikia.
