Necro-cube

Ray, a brilliant engineering student, met an untimely end, only to awaken as Ra'ay, an impoverished orphan on the verdant Green Earth. In this world, humanity wields Magi Cubes, summoning allies to combat monstrous incursions from the ever-shifting Void. Ra'ay receives a defective Necro-cube, capable of summoning a horde of weak undead. While others dismiss it due to its inability to level up its summons, Ra'ay, driven by his inherent need to optimize, views this flaw as his ultimate engineering challenge. Can his ingenuity transmute a 'cursed' artifact into the ultimate weapon, or will the crushing reality of the Void devour him before he can re-engineer his destiny and secure his place in a world that values power above all else?
