Ep 1. The Magnificent Blade, Rin Onigawara

In Armed Girl's Machiavellism season 1 episode 1, titled "The Magnificent Blade, Rin Onigawara," we are introduced to our protagonist, Fudo Nomura. Fudo has been expelled from his previous school due to his violent behavior towards bullies who tormented his friend. Now, he finds himself in a new school, where he hopes to start over and leave his past behind. However, the new school he's attending is not an ordinary school. It's a school exclusively for girls who are skilled in martial arts.

Upon his arrival, Fudo is immediately confronted by a group of girls wielding wooden swords. They demand that he apologize for accidentally bumping into them. Fudo initially tries to reason with them but quickly realizes that their minds are made up, and they won't listen to reason. Eventually, Fudo agrees to apologize, but the girls continue to attack him anyway.

Just when things are looking bleak, a beautiful girl named Rin Onigawara appears. Rin intervenes and puts the girls in their place, proving that she's not someone to mess with. Rin also takes an interest in Fudo and decides to take him under her wing, much to Fudo's surprise.

As the episode progresses, Rin introduces Fudo to the school's unique culture. She explains that the school has a set of rules that all students must follow. These rules are called the "Five Ruling Swords," and they dictate how students should behave and interact with one another. The Five Ruling Swords are:

1. No killing 2. No severing of limbs or organs 3. No hiding one's true nature 4. No disobeying higher authority 5. No unnecessary damage to common areas

Fudo quickly realizes that this school is not like any other school he's attended. The students use swords instead of books, and the curriculum includes lessons on how to fight. Fudo is amazed by the students' combat skills, but he also realizes that he's in over his head.

Throughout the episode, Fudo tries to navigate the school's rules and culture while also coming to terms with his own violent tendencies. He's also trying to find his place in a school that's dominated by girls.
