This show is about a man who is the "finest assassin" (hence the title), who is killed and reincarnated into a new world. Just the start of this post should alarm you to the plethora of sinful content to be found in its frames (would have said pages, but it's an animation, not a book).
Immodesty
As with most anime, this one, too, has immodesty present throughout. A lot "of cleavage is shown throughout the show."¹ On top of this, "Commercial breaks are started and ended with images of the characters naked while their very sensitive areas are covered up[—]such as nipples and groins. However, the shape of the breasts is clearly shown."¹ Such things should never show up on a child of God's device screens.
"In like manner also, that women adorn themselves in modest apparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array;" (1 Timothy 2:9)
Pedophilia
The main character is a full-grown man reincarnated into a new world. He retains his memories and has a harem. This harem includes a 12-year-old and a 14-year-old. While he is only 14 in this new world, as mentioned, he retains his memories. He is a 14-year-old boy with a middle-aged man's mind. Combined with the way those girls are sexualized, this is pedophile activity. Utterly disgusting.While these girls do not physically know him, the fact that they're being sexualized like this, and that they are "love interests," is very concerning. The Bible teaches that such things should only be for those who are of marrying age. For more information, see my post Anime's Unholy Fetish: No Innocence in Loli Culture.
Abused Women
Several woman are forced into an orphanage where they are sold as prostitutes and physically abused."Pervy men touch teenaged girls and children inappropriately. The girls are sex slaves and are sold for a night to be raped frequently. No rape is shown, but heavily implied by dialogue and the reaction of the girls as they return home and when they leave, looking distraught in elaborate skimpy clothing."¹
This, of course, on top of the immodest clothing, is utterly wicked.
"Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body." (1 Corinthians 6:18)
Murder
A major theme of the show is murder. This should have been obvious from the anime title, "The World's Finest Assassin..." Murder is the unlawful killing of a person. What did God say about murdering another human?"Whoso sheddeth man's blood, by man shall his blood be shed: for in the image of God made he man." (Genesis 9:6)
"Thou shalt not kill." (Exodus 20:13)
Killing a man (unlawfully) is wrong. We should not watch shows which contain such violence. It is against God.
Magic
This show contains a lot of magic as well.² As God states in the Law He gave to Moses, "Thou shalt not suffer a witch to live" (Exodus 22:18). In another place it states "There shall not be found among you any...that useth divination, or an observer of times, or an enchanter, or a witch" (Deuteronomy 18:10). Magic is anti-Christ and anti-God.Conclusion
There is much morally wrong with this anime. There is no way to even attempt to defend the indulgence of watching it. The show is morally reprehensible and should be avoided.
