Hourou Musuko Wandering Son is a coming of age manga/anime about Nitori Shuichi, Takatsuki Yoshino, and some of their other friends as they transition into a new school year and struggle with social issues, such as peer judgement, and physical issues, such as puberty.

Now, Crunchyroll's description of the anime reads, "Nitori Shuichi is a boy who sees himself as a girl. He transfers to a new elementary school, and there, meets Takatsuki Yoshino, a tall and attractive young girl, who also dreams of being the opposite sex"

Nitori, is not a boy, but a mtf, and therefore a girl. Same applies to Takatsuki, but he is ftm. Crunchyroll's assertion that Nitori only sees "himself" (in reality herself) as a girl and vice versa for Takatsuki, but is not one is very plainly transphobic. Along with that, uses he/him pronouns musgendering Nitori.

The series even protrays struggles of transgender people, and the manga ending in Nitori using a female name at her work place, though not shown in the anime and Takatsuki experiencing clear physical gender dysphoria in the manga as well, even more so than the protagonist.

Just because it's not inculded in the anime, does not mean it should be left out, even from the first episode it is clear they are both transgender.

A more suitable description would be along the lines of 'Nitori Shuichi is a girl, who unfortunately was born as a male. She then transfers to elementary school, and there mets a boy named Takatsuki Yoshino, a boy who also shares Nitori's misfortune in being born the opposite sex."

Please Crunchyroll, please change the description to match their pronouns and genders they desire.
