I do not own Naruto or Blue Archive, they are owned by Masashi Kishimoto and Nexon respectively.
I'll let whoever picks this up decide how they want to write it, I wish to see some Naruto and Blue Archive crossover stories be made cause Blue Archive has quickly become one of my favorite games. I started playing it near the launch of the game and I still play it. The story is captivating and the characters have great designs for the most part. It's hard to not grow attached to the characters with the main story and their relationship story. The music is amazing as well! A basic answer for my favorite ost is Unwelcomed School but the game has plenty of great tracks. Give it a try if you never tried it and you happen to see this!
The reason why Naruto specifically is because I like Naruto, simple as that.
If some ideas are needed I can provide some. Message me about it and I'll reply to you whenever I can!
