### Summary
Saitama's nonchalant infiltration of the alien warship culminates in a direct confrontation with its leader, Lord Boros, a being who, like Saitama, is cursed with crushing boredom from a lack of worthy opponents. The prophesied battle begins, and in a shocking, series-first moment, Boros actually survives Saitama's punch, his restraining armor shattering to unleash his true power. While the S-Class heroes remain locked in a desperate struggle against the formidable Melzalgald on the ground, Saitama may have finally found the challenge he has spent years searching for. The chapter also features a humorous interlude where a still-reverent Genos receives Saitama's simplistic training advice, much to the cyborg's confusion.
