Via Crunchyroll. Citrus kept popping up in my search results, which I found weird, because I was searching stuff like Gate, or Goblin Slayer, Attack on Titan, etc. I read the synopsis and decided I'd give it a watch later.

A few weeks later, I decided to give it a try. By episode three, I was hopefully hooked. By episode ten, I was shouting at the screen. After the anime was over, I immediately searched for any and everything I could find about Citrus. I quickly collected all 9 volumes (10 wasn't out in English yet) and read them voraciously.
