Nana is one of the kindest and has a passion for helping others. We see Nana go out of her way to help people like her dedication to helping Haru and Subaru. Her kind-hearted nature isn't solely reserved for her customers, we also see how sweet Nana is when she helps her brother by getting his booked signed by Subaru

While Nana loves all people and animals she comes across, she has a special love for cats. Nana owns two cats of her own and is incredibly knowledgeable when it comes to taking care of cats. She is constantly sharing her knowledge with Subaru in order to improve Haru's life. Her love for cats can go to an extreme sometimes as she scolds Subaru for the way he takes care of Haru, but it is still nice to see how much she cares.

In episode nine, we get some of the best Nana moments in the anime. While we usually get to see the kind and cheerful side of Nana, during Subaru's book signing we get to see a much more bashful and flustered side of Nana. Nana is cute even when she is embarrassed and stumbling over her words.

Not only is Nana kind, but she also has an incredibly cute design. The bright colors of her hair and eyes add to the warmth of her character and match her kind personality. Nana also has some great facial expressions that range from heartwarming to hilarious.

After hearing about Haru’s weight gain, Nana heads over to Subaru’s house to give him some advice. Out of all of Nana's appearances, the fifth episode gives us the most Nana content. The episode has a little bit of everything, showing off the best parts of Nana's and fleshes out her character. We get to see Nana's kind-hearted nature, her serious love for cats, and we learn about her family including her two cats and her brother.
