Stolas

Stolas  is a minor antagonist in Love Tyrant. He doesn't speak; instead, his mood is determined by his eyes.

Refuted by the townspeople as "Stolas the Demon," Stolas is an anthropomorphic penguin noted for his violent tendencies. Years ago, had taken an interest in Aqua Aino - the young sister of Seiji Aino - and he attacked the two before getting apprehended. He was sentenced to a cage for years, at least until he escaped, and continued his pursuit of Aqua.

Stolas makes his first appearance in the third episode of the series. After having a nightmare over the sociopathic penguin, Aqua becomes distraught over how despite all of her efforts to become less girly, her brother seemed to ignore her. When Guri and Yuzu go to find Aqua after she had angrily left, Stolas reappears, and he chases Aqua into a tree. Guri arrives to the park a few hours later, and is amused by the penguin. Believing that it was just an ordinary penguin, Guri attempts to prove her point by petting Stolas. However, Stolas abruptly pecks her face in, stating how he shouldn't be handled that shamefully. Having been informed of the bird's return, Seiji arrives at the park in the nick of time, and shouts to Aqua to jump. After an initial hesitation, she jumps from the tree, causing Stolas to crash his head onto one of the tree branches. Stolas is then arrested.

Somehow Stolas escapes, and he continues his hunt for Aqua. In episode six, Stolas attempts to molest Aqua whilst she's swimming. Akane interjects and proceeds to brawl with the depraved bird. Stolas lays several blows on her, and makes a jump for Aqua. At the last minute, Akane grabs Stolas by his beak, and tosses him into the air. Guri tosses Akane a bat, and Akane sends Stolas soaring.
