Because it got irritating, Eris left the dojo. After leaving the dojo, she walked straight forward. She found a peninsula with no one else around, and there she did her practice swings. For food she would eat what she brought from the dojo's kitchen, or she would kill and eat monsters that attacked her. Because it was winter she brought firewood from the dojo which she'd light with magic. When she became tired she'd return to the dojo and slept as much as she wanted.
Eris had already continued such a lifestyle for half a year.
