The event that marked Chouji's ascent into adulthood was not related to any of the more traditional rights of passage for a man.
It was not when he received his hitae-ite, the symbol of his worthiness as a shinobi of the leaf. He was still much too young at heart then to feel the full weight of what it meant. Nor was it his first major victory in battle. That only served, as he was brought home clinging to life by a mere thread, to prove just how much more work there was to be done before he could consider himself dependable. For a brief moment he felt it, when presented with his earring by his beloved sensei, but now the metallic stud was a reminder of what he could not protect. And when he had the chance to redeem that, even just a little bit, by standing against the shell of his former leader, his courage failed him. No, his first experience with war did not celebrate him as man either.
Instead it happened on a quiet night, a few weeks after Chouji's twentieth birthday, in a dimly lit alleyway behind a seedy bar.
On the way back to his cheap apartment after a two day patrol mission, he came across a group of men harassing a young woman. As he approached, intent on breaking up the gathering, he realized the woman was none other than Ino and that, despite putting up a brave front, she was physically overwhelmed. The fire in his chest caused him to react more violently than he ought, though no serious injuries were inflicted, and it was soon just the two of them.
"I was just leaving, you know. I didn't ask them to follow me." The girl's gruff voice, thick with muted emotion, broke the silence between them as she held her chin high. "It's not like I flirted with those idiots. Hell, I didn't even talk to them. Just because a girl's got a reputation doesn't mean she'll screw anybody that asks."
"I know." His hushed reply was accompanied by his hand gently resting on her head. "You're not that kind of girl."
"How do you know?" Her demeanor was still a bit defiant, but her eyes watched him carefully, testing what he had to say next.
"Because you only do it if it's for a mission and even then, it breaks your heart. If any of those idiots paid half-attention, it'd be obvious." He covered her hand with his. "Come on, I'll walk you home."
When they reached Ino's apartment, she pulled him down, tugging timidly on his hair. "You're a good man, Chouji," the blonde whispered into his ear. "Thank you."
Then, she kissed his cheek and ran inside without looking back.
Chouji stood there, fingers lightly touching his cheek, awestruck. And as he pondered her words, he decided he would do his best to live up to them.
