While he spoke, he watched Hinoe carefully to ensure she was listening. Thankfully, he had nothing to worry about.
A marked improvement from her daydreaming of their first few lessons.
"I wonder..." A trailed thought, his mind turning to thoughts of Nara Shun. Another student of his with similar tendencies.
"Is it something to do with me?"Though Izusa had experience in shinobi matters, and was more skilled than his laidback instructor act might let on, he was clueless in other areas. In his youth, he'd been infatuated with his own sensei, Sarutobi Hinari, but that only lasted until after his Chūnin Exams. Once he was recruited for his true work... many things in life lost their appeal.
Romance, love, joy— these were experiences meant for people, not masked wraiths who haunt and hunt others after dark.
"Lovers, stars themselves, must part." He mused on a poem to himself as he thought on the situation... and then,
finally, it dawned on him. The blushing, the nerves, the bashfulness of his students...
"...oh." He thought.
"Oh dear."Briefly, the instructor's eyes widened in concern. Childhood crushes were a natural thing, but if they ever evolved into problems, he would need to address them.
"Maybe my next lesson should be on power dynamics..." He thought to himself, this train of thought coming to a screeching halt as several puffs of smoke erupted nearby. Izusa glanced to the four bunshins, inspecting each one in turn before settling on the last one. A smoky, unsolid-looking duplicate of herself.
"Hm..." He hummed, ready to advise but as he turned to Hinoe he could already see her glaring at it.
The Hyūga already knew what was wrong, and dispelled it after realizing.
"Close." Izusa said, interlocking his fingers within the sleeves of his haori and raising them so that the fabric fell away, and they could be seen.
"Keep in mind— using ninjutsu is about efficiency as much as it is about potency." He said, performing the same
Hitsuji → Mi → Tora, hand seals that Hinoe just performed. Another puff of smoke ensued, and when it cleared, three exact copies of himself stood side-by-side.
"Additional clones offer no tactical advantage if they aren't all perfect." They said in unison, still smiling. Izusa would allow her a moment to observe and ponder his words, then dismiss the clones.
Sometimes, the solution was as simple as moderation.
"One more time, Hinoe-chan." He instructed, placing a hand to his chin as he watched. Her seals were adequate, her control had been practiced, now she just needed to reel back.
