Tomorou Tenma koi aam ladka nahi hai; uske paas “e-Pulse” naam ki ek kamaal ki energy hai jo logon ki soch aur feelings se banti hai. Is duniya mein sab log “Sapotama” naam ke AI gadgets use karte hain, jo isi energy se chalte hain. Par dikkat ye hai ki Tomorou ki energy itni zyada powerful hai ki uske paas aate hi ye gadgets kharab hone lagte hain.
Ek raat, uske device se “Gekkoumon” naam ka ek ajeeb sa creature nikalta hai aur batata hai ki wo ek Digimon hai jo insani energy khata hai. Ye Digimon tab paida hote hain jab AI gadgets mein koi error aa jaye. Kuch Digimon itne khatarnak hote hain ki wo insaan ki saari energy nichod lete hain, jise log “Cold Heart” kehte hain—is halat mein insaan ek tarah se coma mein chala jata hai.
Jab Tomorou ka bada bhai, Asuka, iska shikar ban jata hai, toh Tomorou kasam khata hai ki wo iska badla lega. Wo “Glowing Dawn” naam ke ek group se milta hai jo in baaghi Digimons ka shikar karte hain. Unka leader, Kyou, use batata hai ki shayad uska bhai abhi bhi theek ho sakta hai. Halanki Tomorou ko ajnabi logon par jaldi bharosa nahi hota, par wo samajh jata hai ki apne bhai ko akele bacha pana uske liye mumkin nahi hai.
