The Quiet Princess, the Knight, and the Samurai Rentarō meets his third soulmate, a shy girl named Shizuka Yoshimoto who only communicates by pointing to words in a book. She loans him her favorite book, which they bond over. Later, Rentarō asks Shizuka to install a text-to-speech app on her phone, and then sends her a file containing the entire text of the book, allowing her to "speak" without breaking eye contact with the other person. Shizuka realizes that since the book was not released in an e-book format, Rentarō must have transcribed it manually by himself. Later, Rentarō asks Hakari and Karane to let Shizuka become his third girlfriend, vowing to commit seppuku if he cannot be a good boyfriend to them all.
