This is a great opener for an anime, I love how Frieren and the others have a very different perspective on time due to their biology of course it really makes you think is living that long really worth it if you keep burying loved ones without fully understanding them since you think everyone has the same amount of time as you do. It's like being in your early 20s without having any deaths in your family or close friends you feel immortal like you still have time but here's the thing you never know when it will come so you need to live like every day is your last.
