After I Turned Twelve, I Began to Study the Meaning of Life.

The world collapses, undercurrents surge; zombies break out, and magic appears! I thought the apocalyptic life would last for a long time, but I didn't expect it to end in one day. I thought I would survive when I reached the safe zone, but I didn't expect to face a massacre. I thought this was just an ordinary zombie virus outbreak, but I didn't expect it to be the beginning of World War III! I thought life would continue like this, but unexpectedly, magic appeared again! I thought... I had nothing, so I wanted to just make do with it, not to dig deep to find the truth or save the world. But in order to protect everything I have, I choose to dedicate myself. Even if I have nothing, even if I know nothing, I will do my best to protect them - my relatives who are not related by blood!
