Satan begins to take over the land of Ente Isla using his armies of demons. His advances are stopped by a heroine named Emilia, and Satan flees through a portal, landing in the human world. He is determined to return and conquer Enta Isla, once he figures out how to get back. Trapped in modern Tokyo, he must disguise himself as a human. However, he becomes passionate about climbing the corporate ladder. Thus begins Satan's life as a working human.¹
Demons and Satan
The first, and most glaring issue, is that this show portrays Satan, regardless of how inaccurate. The very fact that someone thought it was even a good idea to name a demonic character after Satan reveals the wickedness behind the anime.
Why would a Christian involve themselves with such evil? The Bible is clear that Christ and Belial (Satan) have no agreement with each other.
"And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?" (2 Corinthians 6:15)
If we are to "follow his steps" (1 Peter 2:21), and Christ does not fellowship or commune with Satan or demonic forces, then we shouldn't either! Do we, as professing Christians, really want to fill our minds with unclean and impure media (Philippians 4:8)?
Immodesty
Crunchyroll gives a content warning for sexual imagery.² Women are seen in swimsuits, and there are several scenes in which females are seen showing/bathing.⁽³⁾⁽⁴⁾ This is not the kind of content the Lord would have His children watch. We are God's; we are to follow the rules He sets. Just as a parent can set rules about what their kids are allowed to do or watch, so too God has rules about those things!
He has said to keep our eyes focused on the right ways.
"Let thine eyes look right on, and let thine eyelids look straight before thee." (Proverbs 4:25)
If our eyes are to "look right on," to take in what is holy and good, to stray not to the left or right, then let us endeavor to obey! Proverbs 23 is clear that we are to "let thine eyes observe my ways" so that we do not fall to strange women (Proverbs 23:26-27).
Profanity
Next, we'll consider the language contained in this show. There are several profane words in this anime.⁽²⁾⁽³⁾ Earlier, we referenced Proverbs 4:25, but I'd like to also consider the two verses before it.
"[23] Keep thy heart with all diligence; for out of it are the issues of life. [24] Put away from thee a froward mouth, and perverse lips put far from thee." (Proverbs 4:23-24)
If we want to keep our hearts, we need to be diligent about what we allow ourselves to consume and let into our minds. Jehovah God commands, "Put away from thee a froward mouth". This is not an optional "if it affects you," it is a blanket command. Keep the perverse speech away, lest you be like unto it.
Violence
Violence is something that humans often enjoy. But it ought not be this way. I'm not sure if there's a word to properly express this, but many times we get a rush of a "transcendent" feeling when watching violence. When there is witchcraft or powers involved, this feeling seems to be multiplied.
Do you think this is a coincidence? That rush is addicting, pulling you in, hooking the mind with its sinful grasp. Satan knows exactly how to pull us in, and we are to not be ignorant of his devices. The Scriptures are clear that those who love violence God hates.
"The LORD trieth the righteous: but the wicked and him that loveth violence his soul hateth." (Psalm 11:5)
That's a strong expression! Don't take this lightly! I wouldn't want to be one whom God hates. Therefore, we are to keep our eyes focused forward, on the Lord Himself and things that are not contrary to Him and His word.
Conclusion
A satanic anime about a devil working a job in the human world? That makes no sense, and it's not biblical at all. An immodest and violent show where Satan plays house⁵ is supposed to bring God glory?!
