Aráchni is a character in Children of the Whales. He is a member of the Allied Empire, and the Commander of Skyros.
At his first, he appears very cautious and emotionless. However, when he fights Ouni and the others on Skyros, he acts in an arrogant manner, and then panics once the tables have turned. He appears to be very ambitious, and has ignored the commands of higher officers, such as Orca, before.
- His name comes from αράχνη, the Greek word for spider.
- According to a blog post by the author, he is somewhere in his early thirties. 
- Although his fate is more ambiguous in the anime, in the manga he is killed by Orca after shooting him.
