Steak is Niche's "pet" and emergency food supply. He followed her from the Love Someone Down freak show after she destroyed it. He is usually seen traveling on her head, very rarely moving from his perch even while she is battling Gaichuu. He has the ability to sniff out the weak spots of Gaichuu, allowing Lag to fire his Shin Ganjuu at the weak spot, killing the armored insect. Niche has remarked that Steak would taste delicious (hence his name). Steak seems to have accepted his fate as a future meal and appears to have meekly submitted to Niche's (interrupted) attempt to cook him. Steak may be the last of the Kapel Meister, a species that once co-existed harmoniously with the Spirit Insects, and was thought to be extinct. (Source: Wikipedia)
Sten is one of the Four Rakshasa Temple Demons who serve as the Prime Minister's squad of executioners. He seems to think of murdering as "releasing one's soul." Sten is a large man with a heavily muscled build similar to Ibara. He has a long braided hairstyle with hair sticking far out at the sides and bald at the top of his head. He has long bushy beard and mustache, bushy eyebrows, and dark prominent circles around his eyes. Similar to his fellow Rakshasa Demons, he wears armor plating on his forearms. He also wears a large Iron pauldron on his left shoulder. In Chapter 36, Lubbock hits him with a spear made of threads. Sten is able to withstand the attack, but Lubbock uses the threads that pierced Sten's body to cut his heart into pieces. (Source: Akame ga Kill Wikia)
