Eris failed to protect Rudeus against Orsted in Season 1 causing her to train for it never happens again. Eris succeeded in protecting Rudeus against Atofe the Immortal Demon King in Season 3 at the cost of her life. Her final smile is realizing she saved him

fuck 😭

Makes you view the entire last scene with her differently

In a way, you could easily say Eris was still traumatized and taking control of that helpless situation she experienced with Orsted in TP 2

I didn't even catch the fact that this was the reason for her smile. This episode cooked way too hard.

I plan to do a big video discussing everything in-depth tomorrow

I'll be there man.

F man… STFU I’m already sad.

Eris is the best waifu😭

Mushoku Tensei's Diary episode to Game of Thrones Red Wedding.

even as a LN reader I wasn't even remotely prepared, what the fuck man, the rage and sadness this ep made me feel...

This is false. The Eris we've been watching is not dead. Why are people unable to split timelines, are they so simple emotionally or intellectually that they fail to separate people?

Anime of the year and Anime of the decade without a doubt.
