Reaction detected to the front right! Stay on Route 3!
"Roger that—wait, are you on-site again!?"
Hearing the voice over the comms, Seita couldn't believe his ears.
An operator should be giving instructions from the safety of the control room, but Guest always finds an excuse to jump to the front lines for rescue work or situational awareness. Every time, Seita has to worry not just about the villains but also about his childhood friend's location while racing through the battlefield cloaked in lightning.
