He's different than his father.
When Sesshoumaru reaches adolescence, Touga begins to train him in the art of war, and Kimi listens daily with no small amount of amusement as her mate vents the frustration that is instructing their son.
She tries not to laugh as he paces the hall in front of their rooms, claws clacking in irritation against his armor.
"Kimi, he is not interested."
Clamping her lips together she averts her eyes and happens to look out the window and find the offspring in question lounging against a tree with a scroll—of what she was not sure.
Sesshoumaru is growing and still perfect in her eyes but stubborn.
"Is his performance inadequate?" she asks her mate, eyes sliding coyly to his.
Touga glares. "Inadequate?" He storms over to the window and points angrily at Sesshoumaru. "That gangling mess of limbs will barely lift a hand to his opponents. Says he's bored and has better things to do." He scoffs, folding his arms across a broad chest, and then looks back at her. "Would rather play with those damned dragons than learn to hold a sword."
Kimi laughs then, and Touga growls.
"I fail to see the humor." Annoyed gold sends a withering look back out the window, but it only lasts a moment before it falls in resignation. He drags his hands down his face. "He is too skinny. How is he to build any strength or muscle if he's going to sit under a tree all day?" His look grows more concerned. "Skill?"
With a shrug, Kimi leans on the ledge of the window, continuing to watch their son. "Perhaps he isn't meant to be a warrior."
Touga's face is deadpan, and he points between the two of them. "That is not possible." He joins her at the ledge. His look becomes contemplative. "He should be the strongest of them all."
Reaching over, Kimi takes his hand and gives it a squeeze. "Let Sesshoumaru be Sesshoumaru."
Touga relaxes—fractionally—and she offers a reassuring smile. "Go train your men." Her lips curve mischievously. "It sounds like they did not get enough exercise."
Giving her a look, he kisses her quickly. "Not funny." But he heads back out leaving her alone.
When Kimi glances back out into the garden, Sesshoumaru looks up and flashes her a grin.
She shakes her head, smiling. "Mulish pup."
