ThomaLumi is the het ship between Thoma and Lumine from the Genshin Impact fandom.


At the start of the Inazuma questline, Thoma is shown seemingly waiting for her. Thoma calls Lumine as a honored guest, Beidou introduces Lumine to Thoma, Thoma waves and chuckles, telling that Lumine doesn't know how long he has been waiting to see her. He becomes her guide through Ritou, trying to get her traveling permit and going through the process of her application at Outlander Affairs Agency. Thoma calls Lumine a good friend while at Outlander Affairs Agency.

When Lumine went to the Komore Teahouse, Thoma was hiding and teases Lumine, pretending to be Taroumaru who is a shiba inu. Thinking that Thoma was a shibu inu, sooner or later, Thoma showed himself laughing, saying that he had his fun. And after that, Thoma apologizes Lumine for the "test" though it was quite necessary. Thoma then guides again Lumine into some places before letting her meet Ayaka. When helping Ayaka fulfill 3 wishes, Thoma tells Lumine that he's sure that she'll do great to fulfill the 3 wishes. Coming back to the Kamisato Estate to inform Ayaka that Lumine has fulfilled the 3 wishes, Thoma appears and pats Lumine's shoulder while meeting Ayaka in front.

After rescuing Master Masakatsu, Lumine goes back inside of the Komore Teahouse, Thoma exclaims now that they're one step closer to victory and they couldn't done it without Lumine and Yoimiya. He chuckles, saying that Lumine turned out to be much more reliable than he expected. Lumine thanks him for the compliment.

Thoma, Ayaka and Lumine all enjoy a hotpot game together, strengthening their friendship.

During the second act of the Inazuma questline, Thoma is revealed to have been captured by Baal and Lumine has to go to save him. As she stops Baal from capturing his vision, she then loses in a fight against Baal, thus leading to her presumed execution. Just as Baal is about to kill her, Thoma frees himself from his binding and throws a spear right at Baal, which forces her to stop her execution. This then saves Lumine's life, who makes a quick escape with Thoma, fleeing the scene. Thoma tells Lumine to go to the resistance as he cannot go anywhere besides stay in the Komore Teahouse since it will be unsafe to go anywhere besides that.

Going to the place where the cats and dogs were, Thoma talks about how he brings the stray cats and dogs some food for them and said that it's like a tradition over the time for him, it felt like a chore, but sooner or later, he started to enjoy it. Lumine mentions that they seemed to like him a lot, which Thoma asks if she really thinks so, well he told that if she feeds them enough then maybe she can she'll win their affection as well. Thoma asks Lumine if she can try and feed them. He mentions that he has some of their favorite food so just she can get their good graces, Lumine then accepts it. Thoma mentions again that he trained them enough to not be aggressive towards humans. Thoma tells Lumine that she's a very approachable person as she comes up to them and tries to feed them. After accomplishing on trying to feed them, Lumine goes back to Thoma. Thoma starts talking about ninja dog and while talking about it, Thoma told that he tried patting them on the head to gain trust but got a nasty bite instead. Lumine tells him that perhaps maybe he should give it some time to calm down.

A Lingering Fragrance

Thoma invites Lumine for a stroll around Ritou, reminding her that it's the place that they both first met. They stop at a nearby jewelry shop and when asked to buy either a necklace or bracelet, Thoma says that both would suit her very nicely. During their stroll he also says, "I'm happy to be here with you this time," implying that he really does enjoy her company.

As the stroll comes to an end, Lumine says there's something she'd like to give him, but he politely refuses and says that "as long as you enjoyed yourself, that's all I could ask for." Lumine insists that he would like it and gives him a Pinwheel Aster, a local specialty from his homeland, Mondstadt. Thoma becomes lost for words at the gift and calls it "invaluable," saying how much he prefers these types of thoughtful gifts over transactional ones.

Although Lumine says she wants nothing in return, Thoma gives her his omamori and says how it can bring the bearer good luck.

The Housekeeper's Other Side

Thoma's Birthday Mail

On January 9th 2022, Thoma gifts Lumine 3 dishes: Butter Crab, Mixed Yakisoba and 'Warmth' (his speciality.) He mentions how he normally spends his birthday with the Kamisatos, but this year he'd like to spend it with Lumine. He also emphasises how much he wants to see her.

“In recent years, I usually spend my birthday with Lord Ayato and Lady Ayaka. But this morning, my lord asked me if I had other plans today... Honestly, I wanted to meet up with you. Lately, I've been worried that you haven't been taking good care of yourself on your journey. As I walk around Ritou, Mondstadt occasionally comes to mind. There are many reasons, but ultimately... It's because I want to see you. Tell me where I can find you! Oh, that's right, leave dinner plans to me. Don't worry about it. I'm on top of my game today and I'm sure you'll be well satisfied. If there's anything else you need, just let me know. Don't be a stranger! I'll be sure to bring everything along!”

Thoma bares a lot of resemblance to Tartaglia, in terms of appearance and personality, making a lot of ChiLumi shippers enjoy this ship as well. A lot of ThomaLumi shippers also like how sweet and playful Thoma is, making him a good match for Lumine. The Inazuma questline where Baal almost kills Lumine only fueled the ship even more, with shippers loving the fact that Thoma and Lumine 'saved' each other.

As Inazuma has only recently come out, the ship is still very new and there is currently not much content of it. A lot of shippers were uncertain about the spelling of Thoma, so some refer to him as 'Tohama', making there two ship tags.
