Boku Dake Ga Inai Machi [ERASED]
Boku Dake Ga Inai Machi, known as ERASED in the English adaptation, is a drama centered around heavy concepts (like abuse, murder). It's also a whodunnit-style mystery...with hints of time travel. It all sounds very anime-y though the emotion behind the story is so heavy, I wouldn't recommend this show if you're in the mood for a chill anime-binge. This show will weigh on your soul for days after you watch it.
Art. The art for this show is very good. The character designs are simpler and realer than most anime (no bright pink-haired protagonist here). What really stood out to me was the color tone decisions, in addition to the well-drawn scenery.
Story. I can't share too much about the story without spoiling anything but I'll give you this: 5th graders are thoughtful, and adult-like. They are accurately represented in this show. Life is depressing, and sometimes no matter what you do, you cannot change something alone.
With that, I definitely can give this anime 10/10 confidential keys.
Pretty sure it broke my top 5.
