The fixer of Inazuma surprisingly hails from Mondstadt. However, despite now having the chance to return to his homeland, Thoma decides to continue serving the Kamisato Clan as their housekeeper. The position itself sounds trivial, but Thoma loves and takes his job seriously. Like in real life, Thoma also has a supportive role in combat, where he provides shield and periodical Pyro DMG. His release was first hyped as it enables Kazuha with Hu Tao, but the Kazuha + Thoma addition got quickly buried under Zhongli + Albedo pairing.
