Tensei shitara Slime Datta Ken

I REALLY enjoy the anime. I just wish they would remove the small amount of fan-service so I could share it with my nieces and nephews. The main character grows more and more powerful, but it is only because of his desire to protect his people and chill lifestyle. He makes friends with and earns the loyalty of many powerful characters of all types, and yet the action and drama never cease. Love it!

There are some comments about "honker heaven" and "soft and squishy" comments comparing Rimaru's slime form to boobs, but mostly this one scene is the only thing I can think of that is definitely sexually not appropriate for kids. It does not happen, but he misunderstands what an elf woman says and the scene is in his imagination before it is swiftly clarified and he is relieved.
I also think the mass killing of an entire army by him as retaliation for them attacking and killing many of his people is an issue for small children as it treats mass death as no big deal in a way. Children should be clearly taught and understand the value of life before watching this series.
The final, and most obvious theme in the series that should be considered before sharing with a child are the themes of reincarnation and immortality. Again, the value of life and impact of loss should be a solid part of a child's foundational education before introducing such themes.
