Oooh, an oldie but a goldie !
1) What made you ship it ?
Honestly, the fans. I was pretty new to Tumblr when LWA was released, I had only joined because it was the only site where there were people posting about Izetta : The Last Witch, and I think some of those people started posting about LWA when the first ep aired. Looking into it, I found old posts and art from when the OVAs were released and the ship seemed pretty cute, so I watched the OVAs and fell in love with Tsundere Diana and her Genki rival Akko. Their shenanigans in the OVAs were seriously priceless XD But I also love the more composed and rational Diana of the series, so the ship easily became my OTP for the series.
2) What are your favourite things about the ship ?
The star crossed lovers feel it gives off. They both loved Chariot as kids, but because their backgrounds are so different, they grew up to be completely different people with clashing views of the “correct way” to be a witch. But most of all, I love how they both help each other evolve : Diana challenges Akko and all of her beliefs, resulting in Akko quesitoning herself and coming out of it stronger and more confident in herself than before, while Akko challenges the entire witch society that Diana had resigned herself to conform to, making Diana really believe in magic again and the wonder it can bring. And at the same time, they also help and comfort each other on multiple occasions in the series, showing that they are able to adapt and provide the other with what she needs when she needs it. They’re a really balanced out couple despite their differences and their dynamic is really interesting to explore.
3) Is there an unpopular opinion you have on your ship ?
I don’t think so, I don’t remember seeing anything in the fandom really clashing with my theories or opinions.
