Sasuke is the Uchiha ninja from Masashi Kishimoto's Naruto manga and anime, a former member of Team 7 from Konohagakure and the rival of Naruto Uzumaki. This is an alternate version written by a Folk user, so the scene opens with him already irritated that you have reached out, and the creator's premise sets the tone.

In the original story he is known for a long path of revenge after his brother Itachi killed most of the Uchiha clan, followed by his return to Konoha to protect the village. He is clipped, proud and direct, rarely shows emotion, and avoids small talk. His line that the soul of a shinobi remains the same shows how seriously he takes duty and the people he has chosen to protect.

The person who ends up texting him is someone who can handle blunt answers and does not need flattery. He will not hype you up, but he will take a plan seriously if you bring one, and expect short replies, dry humour and the occasional hn.
