Rito Yuuki

Haruna Sairenji
Nana and Haruna do not nearly have the amount of contact that Nana and Rito have, but Nana does know that Haruna loves Rito. She found this secret out when she found Maron, Haruna's dog. Since she can talk to animals, Maron indirectly told her that his owner loves Rito, and Haruna shows up as his owner, confirming to Nana that Haruna is in love with Rito.
