Day 35 here and it's asking What anime crossover would I like to see!? There are so many I could think of but just to limit myself I'll put up these 4 that came to mind first!
The one I want to see the most would be a crossover between one of my favorite shows of all time Log Horizon and another very entertaining anime Sword Art Online!! In a 1-on-1 battle Kirito would probably beat any one from Log Horizon but if all the characters were involved I believe Log Horizon would walk away with the victory! Either way I would love to see this!
I also think a crossover between The Irregular at Magic Highschool and The Legend of Legendary Heros would be pretty cool as well. A futuristic world of magic and a magical world still in the past would have great potential! I would also love to see two of my favorite characters Tatsuya Shiba(Fully Unleashed) & Ryner Lute (Alpha Stigmata Rampaging) go one on one! That would be the fight of the century!!!
The Chivalry of a Failed Knight & Gakusen Toshi Asterisk (The Asterisk War: The Academy City on Water) These shows Aired nearly the same time and have quite the resemblance to one another! Would love to see these two come together one way or another for a croasover!
Haifuri (High School Fleet) & Girls Und Panzer! Cute girls operating tanks and battle ships!?!? What more could you want!!! I think this crossover has soooo much potential to it and I think they would complement eachother really well! This is one I would definitely love to see and would probably rewatch it numerous times!!
