Ren is polite and speaks with a very formal tone, although she is not quite used to handling casual conversations. Having been told as a child to refrain from spending too much time online, she also has difficulty communicating on camera. But considering that Ren is a fairly disciplined individual who manages her time well, she could easily dispense with any form of small talk. Ren believes that she mainly takes after her own mother, given her own unwavering commitment towards making Yuigaoka the number one school in her city.
