Sengoku Collection - Season 1 Episode 4 One-eyed Dragon

Upon arriving in the modern world, Date Masamune is tricked into working for the yakuza and ends up getting thrown into prison after getting caught in a police raid. After a fight breaks out in the showers, Masumune uses the opportunity to escape, determined to get revenged on the yakuza who screwed her over. She confronts the gang boss, telling him to commit seppuku, though soon decides he's not worth killing. Nobunaga then appears to challenge Masamune for her secret treasure, but she decides to postpone her fight in favour of searching for her servant, Kojūrō.
