Ah, Valentine's Day, the worst day to be single.
Demon Slayer just released this 4 episode special to celebrate Valentine's Day, featuring the main cast of characters in a school setting as they're put through different scenarios.
This special is quite basic and is nothing special, it's just more Demon Slayer for those wanting more of the series. There isn't much to say about the production values as Ufotable probably knocked this out in a couple of weeks of production. The artwork is chibi-like and there isn't much movement or fluidity in the animation.
There were some enjoyable parts, but nothing else impressive. You can easily finish this in 10 minutes or so, so you won't lose anything by watching this.
6/10.
