hates Emilia because they think that she's a witch, which is a reason why she lives alone. Additionally we get to find out more about Puck and how he met Emilia. Overall the story is really great, however, you need to keep in mind that this OVA only gives a glimpse of Emilia's past, and moreover doesn't answer major things, such as why Emilia is treated like a witch, but it does answer a few minor stuff in case you're wondering, such as why Puck calls Emilia his daughter.Art 8/10: I really liked the art and how White fox utilized it to convey the atmosphere of different scenes. An example in particular that I liked is the use of the red colouring in the ice, in order to portray a horrific atmosphere. Speaking of ice, if you're a fan of ice powers, you're going to love this OVA. White fox did an incredible job in animating the ice powers and other stuff, such as the spirits and mixture of red and blue fire. The animation was pretty good in some scenes, however, I felt like it was lacking in the fight scenes and there's barely any action on the first half of the OVA so I was expecting better when it came to the fights, but it doesn't have a huge impact on the enjoyment of the ova, so I guess it's fine.Sound 8/10: The OST was pretty great overall and I liked how it was utilized in the appropriate scenes and atmospheres. The ending theme was also great as it is a relaxing song, which fits in the atmosphere and surroundings of the OVA to an extent, with Emilia living a silent life without having much social interactionCharacters 10/10: There's barely a cast of characters in the ova as the main cast is Emilia and Puck (and a few other minor characters), but I feel that's the reason why I gave this section a 10/10. It gave Emilia and Puck more time to express their emotions and thoughts. My favourite of course is Emilia. After I finished the ova I completely agreed with Subaru complimenting her. Even due to her conditions, Emilia is such a kind soul, and that's demonstrated in her repetitive actions. Even if all the villagers hated her, she still showed care about them (which is further proved later in the OVA), and I really loved her at the end of the OVA where she got to express her feelings in front of the evil spirit and Puck. Puck is also an amazing character. He is aware of Emilia's conditions, and instead of being scared or running away, he sticks by her side all the time. I really liked how they handled Pucks internal monologue in the text flashing to show his feelings. Even though we got like 4 secs to read them, it was pretty cool and it reminded me of the monogatari series. At the end, Puck also gets to express his emotions in front of Emilia, which made me to respect him even more.Overall 9/10: This OVA was great and it was a great opportunity to learn more about Emilia and Puck ans their place in life, even though it was a small glimpse of their past. If you're a hardcore re:zero fan or a fan of the anime in general, I highly recommend to watch this OVA, it will make you have more respect for both Emilia and Puck
