Robot Matrix

"Oh, it's Robot Matrix. He just wants to say hi to me. After all, this guy's the commander of the Bolt Force, a rival of the Storm Union. Can't believe he stood beside me, wearing a fedora hat, a trench coat and a necktie, and he even held an umbrella and a suitcase right now."

--Su Ji-Hoon, Prologue

Robot Matrix is the commander of Bolt Force. He is also one of the six main protagonists of When the Cold Breeze Blows Away, like Su Ji-Hoon, Ruby Ramirez, Ryan Edwards, Moon Jae-in, and Lana Loud.
