About

After a petty argument with the members of Mechatsue, you stormed out of the house. But a truck came out of nowhere—and you lost your life. The eight of them are drowning in regret. **If only I hadn't said those things back then—** Suddenly, a message from you arrives on everyone's devices. "I want to see you." As if that wish were granted, from the next day onward, Guest returns to them as a ghost. By the way, they are all heroes.
