Tsuna always looked up to Kyoko, and Kyoko always looked up to Tsuna. Each found a strength in the other that they could only hope to achieve one day. Neither of them knew that, and that was the most ironic part of their story. And so they both sat in silence, wishing and wanting to be friends with the other.
They didn't become friends. At least not for a while they didn't. The self imposed social hierarchy in Namimori prevented him from even trying without being beat up behind the school. Hibari always managed to find out when it happened, and 'bit him to death for being a pathetic Herbivore'. Hibari's jacket always managed to flap like there was a wind (there never was, the area he was in prevented any wind, and Hibari never moved that fast. Maybe the wind was intimidated by him?) as he walked away. Not long after that time, he stopped trying to talk to Kyoko.
But it wouldn't be the last time he would see (or be beaten up by) Hibari.
A few years later, the first kaiju made landfall in San Francisco, and everything changed. Most brushed it off as a one time thing, but the smarter people knew it was only the beginning. Many tried to deny it had actually happen, and not a reality that would continue to get worse and worse until it wasn't. But that is a time that wouldn't come for a while. Not without many losses.
The reality of the situations wouldn't affect Namimori until a Kaiju made fall on Japan, and destroyed Namimori on its path of destruction. Killing many and putting one Sawada Nana in a coma, leaving a seventeen year old Sawada Tsunayoshi to take care of his three adopted siblings. But that only lasted for three months then the Hibari Clan took him in as a favor to Nana (she was the Hibari Matriarch's sky for some odd reason) after she was put in a coma by the kaiju named Ken.
