The Boys focuses on a world filled with corrupt superheroes, so Kimiko’s innate goodness shines a little brighter–and it’s accentuated by how she communicates. While she does communicate with her team, the majority of her communication is between her and Frenchie. Their relationship, which has consistently teetered back and forth between platonic and romantic, is built upon their unique style of communication, as the sign language they use is not ASL or any other previously known form of sign language.

The Origin Of Kimiko’s Sign Language In The Boys Explained

Kimiko’s sign language in the show is actually a completely original form of sign language. Actor Karen Fukuhara worked with sign language coach Amanda Richer–who was Sally Hawkins’ coach during the filming of The Shape of Water–to create an entirely unique form of signing. According to Insider, Fukuhara’s entire portrayal of Kimiko in The Boys has been shaped by her relationship with Richer, specifically relating to her perspective living in a society that isn’t always mindful of those with disabilities.

In the show, the language was unique to Kimiko and her brother Kenji, which allowed them to communicate with each other with no risk of others interpreting what they’re saying. Starting in season 2 of The Boys, Kimiko teaches Frenchie the language so that the two of them can communicate more effectively. Their connection through this style of communication elevates their relationship even further, and will likely see them continue to muddy the waters between romantic love and platonic love.

Why Fukuhara’s Kimiko Is Better Than The Comics Books

There are several notable differences between the on-page and on-screen versions of Kimiko Miyashiro, but one of the most significant is the reason that they can’t speak. In the comics, Kimiko–or rather “The Female” as she is known on the page– has selective mutism but the writers offer no explanation as to why that is. However, in The Boys, her selective muteness is a by-product of the trauma she suffered as a child and young adult. The created sign language she shares with her brother and eventually Frenchie is the ultimate symbol of her confidence, as she only communicates with those who have earned her trust and loyalty.

That level of backstory and expansion of Kimiko’s personality is what makes Karen Fukuhara’s version of the character in The Boys so much superior to her comic counterpart. It also showed that the writers were also making work on their promise to flesh out Kimiko’s character more after they faced a backlash for perpetuating negative stereotypes towards the Asian community.
