The hero died and they asked Makoto to fill in until they find a new pilot

Makoto keeps surviving by refusing help, even when it costs him everything. Then a sealed pilot AI named Hina starts speaking to him through the cockpit, and the one thing he has always avoided becomes the only way he can stay alive. His past life in the cockpit gives him answers that save him in lethal fights, but it also ties him to a dead friend, a silent memorial, and a wound Hina has to treat in front of everyone. He wants to keep his distance. Hina keeps measuring the days left in his life. The person he cannot afford to need is the one he starts to love.
