Mashruuca Alicization, mashruuc dawladeed oo sir ah oo ay maamusho Rath, oo ah shirkad xiriir la leh Ciidanka Difaaca Is-difaaca ee Japan (JSDF), ayaa la bilaabay in ay abuurto midkii ugu horreeyay ee heer sare ah, «Bottom-up AI». Adigoo isticmaalaya jiilka 4aad ee FullDive machine, loo yaqaan Soul Translator (STL), Rath wuxuu ku guuleystey inuu koobiyeeyo Fluctlights (nafaha) ee laba iyo toban caruur ah oo dhashay, abuurista «Soul Archetype», Iftiin macmal ah oo aan horumarinayn oo la koobiyeeyay si loo abuuro cusub Fluctlights macmal ah, oo markaas u baahan doona in la koriyo si ay u bislaadaan shakhsi ahaan. Sababtan awgeed, duni macmal ah, oo loogu magac daray «Underworld», ayaa la sameeyay iyadoo la adeegsanayo nooca kernel-ka bilaashka ah ee Nidaamka Cardinal, Seed, ka dibna loo wareejiyay guud ahaan STL iyada oo loo marayo muuqaalka Mnemonic Visuals ee STL. Underworld waxa ay ku beegan tahay wakhti hore, oo cilmiga iyo falsafada uun la daah-furay, balse halkii laga abuuri lahaa waayihii hore, dhul kooban iyo caadooyin gaar ah ayaa la soo bandhigay si dadka dunida ku nooli ay u samaystaan bulsho iyaga u gaar ah.
