Is it a sin to watch Call of the Night?

Call of the Night is an anime about a boy who becomes fascinated with the nighttime world and a vampire girl, involving romance, supernatural themes, and some sexualized content.

We're now going to evaluate it using the following simple but effective test:

1. Does it glorify God?

No. Its themes and worldview are not centered on glorifying God, and it contains supernatural/vampire elements that conflict with biblical teachings about darkness and the occult (Ephesians 5:11).

2. Can I do this without being tempted to sin?

No. The series contains sexualized scenes, suggestive dialogue, and romantic situations that can readily encourage lust (Matthew 5:28).

3. Could I do this with Jesus Christ next to me?

No. Given its sexualized content and themes involving vampires and supernatural darkness, it would be difficult to honestly say that watching it is appropriate in Christ's presence.

So, yes, it is a sin to watch Call of the Night.

The main issue is not simply that it is anime, but that this particular series contains content and themes that can conflict with purity and a Christian's call to avoid participating in darkness.
