Third person POV
On Rummshi's planet in Universe 10, Y/n Black trains rigorously. His current sparring partner was Cus.
Cus: You're doing great, hon! You're even stronger than Lord Rummshi!
Y/n Black: While I appreciate you saying that, I can't even consider stopping here. If another God Slayer incident were to happen, I can't stand idly by this time! I must serve Justice!
Cus giggles at her partner.
Cus: It's always nice to see you all fired up. Alright then, come at me, no holding back!
Y/n Black closed his eyes and takes in a deep breath, his aura engulfing him before he slowly exhales, his aura flaring out before condensing back around him, gently flowing like a river. He had activated his own version of Ultra Instinct. He called it True Ultra Instinct. It appears to be a mix of his usual Ultra Instinct and Goku Black's Rosé form, due to Zamasu being part of him. His eyes were grey and his hair was silver, but he had a pinkish silver aura around him.
Y/n Black: Here goes nothing!
He rushes Cus, who dodges his attacks with relative ease.
Cus: Come now, my dear.
Y/n Black smirks however, for he had a trick up his sleeve.
Y/n Black: Kaioken!
Cus: Kaio-what?
Black kicks her away and fires several Ki blasts at her, which she barely dodges, but he then knees her in the gut.
Cus: So, you used that new technique and some Ki blasts to throw me off? How cunning~
Black: I learned this ability during my time with my counterparts, but I only just recently mastered this power.
Cus smiles at her lover and kisses his cheek.
Cus: What a brave and gallant defender! By the way, have you seen Gowasu lately? Surely you haven't forgotten?
Y/n Black's eyes widen.
Y/n Black: Thank you, dear!
He uses Instant Transmission to teleport to Gowasu's planet.
Y/n Black: Master Gowasu? Hello?
Gowasu: Come inside, come inside. I just made tea.
Y/n Black nods and walks into his master's home. Currently, he was watching GodTube.
Y/n Black: GodTube, again?
Gowasu: I enjoy my bouts. Come join me.
Black nods and walks over, sitting next to Gowasu and taking his cup of tea.
Gowasu: How's your training coming along?
Y/n Black: I've made much progress, master, but not nearly enough.
Gowasu: Hm... Y/n, I believe you push yourself too hard.
Y/n Black: But-
Gowasu: Just listen... I understand you wish to prevent any future attacks, but you need rest too. You look like you've slept once in a week. Training is good, but after so long, it's torture, not training. Take a day off.
Y/n Black: ... That's what you think I should do?
Gowasu: Yes. Spend time with your woman. Conceive an heir.
Black blushes furiously and looks away.
Y/n Black: Thanks, master Gowasu.
