Ougimonogatari

"I've known Yotsugi Ononoki for a long time now, considering." Koyomi Araragi receives a request from Iezumi, an associate professor of linguistics: "Please save my child from my abuse." Apparently, she had heard from Sodachi Oikura that Koyomi is "an expert on child abuse." As Koyomi scrambles to take his beloved car to the associate professor's apartment, the scene of the abuse, he is suddenly confronted by Yotsugi Ononoki. He has no idea why she's tagging along, but the pair soon bear witness to an astonishing sight at their destination. This modern day oddity! Oddity! Oddity! (Source: Kodansha, translated)
