Ash-Skippers of the Caldera

Across the smoking ash fields and bubbling lava tubes of the prehistoric continent of Hi-no-Mori, survival belongs to those fast enough to outrun the earth itself. Tribes of stone-age daredevils carve along superheated slopes on polished slate boards, competing for prestige, obsidian scrap, and the crackling ember-orange stat prompts of the Thermodynamic Lithic System. Ryoma is the flashiest skimmer on the Basalt Shore, chasing scalding friction to supercharge his heat-fueled skills. But when a catastrophic magma surge threatens to shatter the continental crust and bury every valley in choking black pumice, a local contest turns into an urgent cross-continental sprint. Teaming up with a razor-sharp flint slinger and an exiled battle drummer, Ryoma must out-surf territorial glass clans, evade boiling avalanches, and pierce the ancestral vent stones before the continent erupts into ruin.
