[Haikyuu!! fanfiction + double identity + a little System progression + making up for regrets]
He is Uchinai Tenma, former Little Giant of Karasuno, current fearsome assistant coach at Kamomedai, and part-time manga artist.
With the [All-Knowing System] in hand, he can see everyone's potential.
Faced with doubt: “Can someone that short even play volleyball?”
He answers with a god-tier receive: “Watch closely. This is the very essence of volleyball!”
After leading Kamomedai to a championship, he keeps a low profile, heads to Miyagi for a little romance, and takes over Karasuno along the way.
Hinata: “Mr. Uchinai is my sun!”
Kageyama: “He's the scariest coach there is!”
Saeko: “Tenma is the most dependable boyfriend!”
First, he leads Kamomedai to the championship; later, he guides Karasuno to national dominance.
In this life, the Little Giant is no longer just a legend. He is a real, enduring king on the throne!
It's nice to watch, but it's not over before I finish writing it. I still want to read it again.
