That night, at the Senju Clan Compound.
Mirai had just finished bathing and returned to his room when Kushina followed him in with two cups of hot milk. She skillfully climbed onto his bed and leaned against him.
"How was training today? I heard you even taught Naori a Ninjutsu?"
"Mm, she learned pretty quickly."
Kushina pouted. "Hmph, you've never taught me anything. No, I'm jealous!"
Mirai smiled and rubbed her head. "You don't have the Lightning Release affinity. Even if you learned it, you wouldn't be able to use it."
"Then you can teach me something else."
"Teach you what?"
"...Forget it. I should just focus on practicing my Yin Seal."
"Tsunade said that once I master it, I'll become strong and pretty in the future."
Mirai smiled and tousled her hair. Kushina narrowed her eyes and rubbed against his shoulder like a cat being petted. The two of them leaned together in silence for a while before she finally returned to her room, satisfied, carrying the empty cups.
It was really hard to imagine Kushina becoming a violent woman like Tsunade.
Could it be that even gentle girls became irritable after getting married?
Not long after he closed the door, it was pushed open again.
Tsunade stood against the doorframe in her familiar white bathrobe, her wet hair draped over her shoulders. "Brat, I knew you weren't asleep yet!"
Mirai leaned against the headboard and lazily raised his eyelids. "Tsunade, you're here again today?"
"What, not welcoming me?" Tsunade walked in and casually shut the door.
Her tone carried the matter-of-fact air of, "I came because I wanted to. What are you going to do about it?"
"Was training tiring today? Are your shoulders sore?"
"I'm fine..."
"Then they're sore." Tsunade patted the bed without ceremony. "Lie down."
