this one starts with a boy that claimed to be Yato's son... But he isn't and he finds out that he hurt that boys grandmother... Because it's found out that Yato is really 300 yrs old.. It also boggles my mind that a 22 yrs old woman is so stupid and naive still. He then tries to interfere in their relationship which kind of works.. I guess they don't talk much cause she just found out be lives forever. It bring them to the boys hometown somehow where she finally finds Yato again after he left a month before. The grandmothers ghost apears and explains everything.. She takes Yato back....
The next thing was her needing to grab a mirror for her boss. And somehow the mirror has moon power to make Yato into a human during the day. He has fun with that but the woman owner of the mirror became weird and vein. She believes her husband has a mistress on the side so she always tries to get attention from men and is obsessed with becoming the prettiest. She tries to do something to the girl but Yato quickly steps in to stop it. The husband breaks the mirror and all ends well.
The last one it's her birthday and they take a trip to a cabin place in the forest that she has gone to before. YAto planned to show her something there. She ends up finding out that the owner is actually her ex- boyfriend. She then starts to quickly have feeling for him again and pretty much kick Yato to the side.. But after she kisses her ex she realizes that she doesn't actually like him again.. She then goes to the place that Yato wanted to show her to wait for him. He goes to search for her there and she is so scared that he doesn't want to bother with her anymore that she flings herself on him and apologizes. All ends well.
