We know anime is considered "cool" among the young children and teenagers of today, for whatever reason. However, most of it is evil, perverted, satanic, violent, and generally bizarre. These anime and manga-based shows like Assassination Classroom have illuminati symbols all over them, and their characters use "determination" to draw upon the demonic powers and gain superhuman strength.
Do you think that Our Lord God is happy to see Assassination Classroom depict senseless violence, witchcraft, death worshipping, and satanic symbols? Ask yourself this, how can a type of entertainment with so many satanic symbols become famous? It’s simple: the devil knows how to entertain. It’s there in the Bible. I urge all of you to read the Bible so you will know the real truth. The Bible will not deceive you at all.
The characters in Japanese anime often are inspired by demonic power, bringing some form of destruction, more than healing, through either physical powers or spiritual powers under the name of ‘chakra’, ‘zen’, ‘aura’, or just ‘spiritual energy’, or so on. All of this encourages worshipping of devils. Read the Bible, especially the book of Revelations, and you’ll see that a lot of the things occurring today were mentioned in the Christian book. Stay blessed people.
