Maybe it's because I was spoiled Koyanskaya's real origin months ago and had time to come to terms with it, but I didn't hate this event as much as others did. I thought it was okay for the most part, though there wasn't much going on because of the heavily reduced cast.
On a completely unrelated note, I'm in need of advice for the GSSR. I'm hesitating between Buster Knights and Quick Extra. Since I now have Skadi and am planning on getting her Summer version, I'm thinking it would be good to expand my Quick roster which I've very much neglected so I'm leaning toward the latter. Are there any servants that pair up particularly well with the Skadis? Can Summer Skadi herself work as DPS?
