I Found Doraemon’s What-If Phone in a Junkyard

While working overtime to deal with the mountains of garbage left by tourists flooding in during the summer peak season, I found one of Doraemon's gadgets in the trash: the What-If Phone Booth.

After confirming that the phone booth was real, I found a battered, broken-down Doraemon as well. I used the booth to repair him, but hidden forces nearly destroyed the world in their bid to seize the future gadgets.

With Doraemon's 4D pocket damaged and the What-If Phone Booth in my possession, we set out in this post-apocalyptic world to build a kingdom that could shelter the survivors, while fighting against a mysterious army of mecha.
