The Strongest Sage with the Weakest Crest

This anime is such a waste of time. Characters dialogs are so dumb and faded its hard to sit through the episode. So, i don't recommend this to anyone.

Without major plot holes and with some entertaining moments, but also with some narration gaps and annoying primitivisms.

Overall, it gets from enjoyable to barely watchable in the last episodes as quantity of entertaining moments decreases and quantity of primitivisms increases.

All protagonists are likable, but shallow. Antagonists are also shallow.

No substantial morals along the way.

No other especially noticeable traits, such as music, fights, emotions?, relationships, world, dialogs, humor, visuals, ideas, moments, etcetera (whether positive or negative). ...

If I am compelled to guess a rating, then approximately 7?

The writer did excellent work creating the world and main characters. However, the story really needed much more depth. If more time was spent developing the depth I could easily see giving this a 9.5 rating. I really liked the idea of this series and found it interesting but always thought the dialog and interactions were mostly shallow and wanting as if it were a children's fairytale. After saying that to everyone reading this... I still would like to see more.

From what I can tell, people want to label this as a typical overpowered main character with a gaggle of girls isekai. Well, the main character is only interested in one of the girls and only one is interested in him, so definitely not a harem. Yes, the main character is overpowered, but even he sees something wrong with that. He wakes up thousands of years in the future (of his own world, not another, and on purpose) to find that the strengths of humanity have taken a major downfall. He spends his time trying to figure out why this has happened to humanity, how deeply ingrained into human society demons must be to have caused this, and trying to power up those around him in an attempt to restore some of humanity's power. If anything, this is far from the typical isekai where someone lands in another world.
