Okami-san and Akazukin-chan, and While We're at It, Ryoshi-kun - S1.E6

Concerned about Ryōko, Ryōshi meets up with Ringo to ask about her relationship with Shirō, though she says it would be best to ask her himself once he gains her trust. Ringo recalls when she first met Ryōko in middle school and saw her true side for the first time. Noticing Ryōko pushing herself and getting into needless fights to hide her true feelings, Ringo came to understand her and offered her friendship. Ryōshi recalls when he started observing Ryōko and inevitably falling in love with her and decides to become stronger so he can protect her.
