Towa has orange hair with a choppy fringe, similar in style to Saburou Suzuki, which falls between his eyes. Towa's eye colour is unknown. He has been depicted wearing a hooded jumper as well as his white uniform shirt. He is taller than Chiyo.
Towa acts indifferent towards his sister. He appears to think that Chiyo is annoying and often tells her to be quiet, especially when she rambles about Nozaki. He does not know that Chiyo is Nozaki's assistant and considers her to be weird for being 'such a big fan' of Nozaki. When a friend asks Towa how he would describe his sister, he explains that 'she wears really big ribbons'.
Due to Chiyo's constant praise and exaggerated descriptions, Towa becomes convinced that Nozaki is a model working under the stage name of 'Yumeno Sakiko'.
Towa's first impression of Kashima as a handsome guy led him to believe that she was Chiyo's idol, 'Nozaki the model'. However, this idea vanishes after noticing that she is wearing a skirt. When questioned about her and Nozaki's relationship, Kashima tells Towa that she is his 'rival'.
When Towa notices Mikoshiba approaching Kashima, he exclaims that 'the hot guys are multiplying'. Kashima tells Mikoshiba that he is a kid looking for Nozaki.
- For the question "Which sibling's backstory would you most like to see?" on the fifth anniversary poll, "Chiyo's younger brother" garnered the largest number of votes. As a result, Towa has been included into the supporting cast.
