『 DROP THE HANDKERCHIEF: Referee Yakou’s Deadliest Variant 』 (A mind-reading duel where hesitation equals death. Each wrong guess injects “near-death poison.” Time, memory, and perception are the only weapons—and you’re facing the man who mastered them even while amnesiac.)

Souichi:

“Perfection is simple. You just remove everything unnecessary.”

[NARRATOR: Intelligence: Extraordinary Genius. Can solves Rubik’s Cubes entirely in his mind and simultaneously solves two of them without any physical input rather than using preset solving methods like CFOP or Roux which are methods developed to solve the cube quickly through a series of step-by-step pattern recognitions he also identifies the most optimal path for any given random configuration and this approach requires a full analysis of all potential move combinations to determine the absolute shortest and most efficient solution unlike conventional algorithms which prioritize speed and ease over optimality but despite the common misconception, Souichi doesn’t attempt every single permutation through brute force. Instead, he mentally models all permutations evaluating, discarding, and refining them with pinpoint accuracy while standard time complexity reductions bring the number of permutations down to more reach quintillion numbers and this still represents an almost unfathomable level of mental computation, this number only applies to a single cube. with two cubes, the base permutation count doubles and realistically, it would be far more due to the increased complexity of simultaneous operations, spatial orientation tracking and inter-cube coordination, in terms of working memory, Souichi demonstrates the ability to store, manipulate and track the state of two Rubik’s Cubes across trillions of permutations in short term memory, his brain functions like a live simulation engine, constantly adjusting, recalibrating and updating information and his  processing Speed involved  must process visual and spatial data at almost lightning speed, assess move outcomes instantly and make decisions with zero hesitation, meanwhile, the spatial visualization  required for this task is two three-dimensional objects in motion, rotate them mentally, anticipate the effect of every move and maintain the integrity of both mental models simultaneously and he sees the current state of the cubes but all the possible intermediate states on the path toward the solved configuration. All these dimensions culminate in his cognitive processing which encompasses Souichi’s ability to logically deduce, calculate and mentally simulate outcomes with extreme efficiency and assessing the relative weight of each index for this feat which can be observed that processing speed surpasses working memory which in turn edges out spatial visualization,the magnitude of this mental accomplishment becomes even more staggering when placed within the context of a high stakes game of Drop the Handkerchief and played against Baku which is noted to have godly intellect and devil calmness, In this setting, Souichi is solving puzzles,  strategising, reacting under pressure and maintaining composure in an extremely cognitive demanding environment as he navigates immense mental strain and multitasks through heavy cognitive load added the heightened by the parallel processing required to simultaneously solve both cubes and despite all of that, Souichi operates in a state described as 'Perfection' and can execute his mental strategy flawlessly. Can figure out Baku double layered trick and Souichi analyzed Baku’s actions and realized Baku had caught on to his echolocation and Baku sitting on the ground and placing a handkerchief or possibly a necktie there, Baku aimed to mislead Souichi, Souichi knew Baku's counter-intuitive tactics from the first round that he wouldn’t risk an immediate death but would prefer to let the drug accumulate and therefore, Souichi concluded that the handkerchief was likely under Baku that was hidden as part of his trick.]
