Great ending, the best part about the anime for me was the MC was very well conceptualized.
Yu is not some perfect MC with a very gentle and caring side, he turns insane and had shortcomings and vulnerabilities as we do. It was his flaws that made me take a liking to him.
Loved all the other characters and the way story had maturity associated with it was amazing to watch.
It's not your generic anime storyline rather it's got its unique vibe you'll feel excited, at times feel heartbreak and also feel hope while watching this great piece of art.
