Tsuto Kaijitsu

Tsuto Kaijitsu is Ameiko's younger brother. He is a half-elf, unlike his sister or parents, making him something of an awkward topic of gossip. He was sent away to boarding school at a young age, and was only recently seen in Sandpoint for his mother's funeral, five years before the goblin attacks on the city. He is a skilled hand-to-hand fighter, and harbors extreme resentment at the town for singling him out, and towards his father Lonjiku in particular. He met Nualia Tobyn while away and gladly became one of her hired mercenaries, all too glad to take brutal revenge on the town he hated.
About a week following the incident at the Swallowtail Festival, Tsuto sent a letter to Ameiko that warned her of their father, implicating him as the traitor who loosed the goblins upon Sandpoint. The note asked her to meet him in secret at the glassworks that night; the letter was found the next morning, but Ameiko wasn't. When the glassworks was investigated, Lonjiku was found dead, along with all of his employees. Tsuto was found in the basement, drunk and violent. Despite the evidence that he murdered his father with the assistance of a band of goblins, he had yet to kill his sister and still seemed to show some sort of twisted care for her, paying lip service to her safety despite the brutalized state she was found in. Tsuto evaded capture, but the journal he dropped in his drunken retreat held plans for the Swallowtail attack, as well as for future attacks. It also made clear an infatuation with Nualia.
The Pandemonium soldiers hunted down Tsuto to the Thistletop Shrine in Thistletop Woods, where he had been hiding out with Nualia and her other mercenaries. They gained the help of the ranger Bruthazmus in attacking him, and they rendered him unconscious, dragging him back in chains to Sandpoint for due process under the law for the heinous crimes he committed.
