Even for viewers, betrayals within anime can sting — a kid may turn against their family, favorite characters may do the unspeakable, and the least suspecting character may not have their friend’s best interests at heart. Sometimes these betrayals make sense, and other times, they’re done to help revive and create excitement in a stale story. No matter the reason, the best betrayals always have a way to pull on the heartstrings.
