Apocalypse: My Pocket Dimension

The extreme heat Apocalypse breaks out. In his past life, Kane was backstabbed by a neighbor. Reborn before the Apocalypse, he builds an absolute defense shelter. When the Apocalypse descends, his mocking relatives and ex-girlfriend kneel outside, begging for water, but Kane turns them away. His neighbors team up with hostile forces to break in, but the shelter remains unscathed. Kane carries out justice and eliminates threats.
