[Crossover] Oh No! The Saniwa Is Depressed Again!

Kiyomitsu Kashuu always thought his Saniwa had a peculiar vibe. It all started with their first meeting. Kitsunegasu: Here you go, Saniwa. This is your starter sword. Why don't you introduce yourself? Saniwa He Sijia: I'm a Saniwa, female, twenty-four years old. No money, no looks, no figure. Lazy, awful, greedy, and gloomy. I have no redeeming qualities apart from spiritual power. Anyway, please put up with me. If you really can't, it's fine to fall into darkness and kill me. I'm such a loser that I don't even have the courage to kill myself. What a disgrace... Ah, have even my words turned gray with gloom...? (Mutters to herself) Kiyomitsu Kashuu: ...Wait, wait, wait?! Kiyomitsu Kashuu, who was supposed to have psychological scars and seek healing from his Saniwa, found himself overwhelmed and took up the mantle of the citadel's leader. Kiyomitsu Kashuu: Everyone, come take a look! Our Saniwa may be gloomy, but she's kind! She may be gloomy, but this isn't a dark citadel! She may be gloomy, but she's incredibly lucky! She may be gloomy... QAQ Citadel comrades: Oh no, Lord Kiyomitsu! The Saniwa/Master/General has gotten gloomy again!!! Kiyomitsu Kashuu: ...She may be gloomy... QAQ... Wait, I'm coming!! We can handle this! Whatever you do, don't let that jerk who's trying to steal our lord find out! Even if you're stuck in the mud, one day a beautiful flower will bloom. Content warnings: 1. My own take on the citadel. Only swords the author owns will appear. (Seal's smile.jpg) 2. The setting is a mash-up of various worlds, including anime and Marvel/DC. It may definitely be OOC. 3. Mostly a healing story. 4. After a month of letting my imagination run wild, I've decided to increase the Marvel/DC crossover content. The male lead is set, and will appear early.
