Description
Akiwo Haza co-leads Team Autumn, formed for a government survival project. Previously a successful internet businessman educated in America and fluent in English and Spanish, his achievements caught the attention of a powerful politician seeking a fiancé for his granddaughter, securing his place in cryonic preservation.

Initially lazy yet highly intelligent and strong-willed, Akiwo adapted to the post-apocalyptic world by focusing intensely on objectives, disregarding the methods required. When the assigned guide, Ryoya Izayoi, proved ineffective, Akiwo and Ran Shishigaki assumed command, imposed strict rules and work quotas, and enforced a ban on reproduction to defy the project's repopulation goal, fueled by hatred for their creators.

After awakening, Team Autumn wandered Japan before settling in Kansai. Akiwo grew pragmatic and resourceful, efficiently organizing labor and managing supplies. His appearance shifted from well-groomed to unkempt, often seen smoking narcotic tobacco. During a conflict with Summer Team B, he interrogated Natsu Iwashimizu, demonstrating his authoritarian control. When Izayoi attempted to poison their water, team loyalty prevented rebellion.

A volcanic eruption destroyed their crops. Upon discovering member Kurumi's pregnancy, Akiwo and Ran sought her execution for violating their rules. Izayoi helped Kurumi, Ryusei, and Akane escape. Later, encountering them at Ryugu Shelter with Spring Team members, Akiwo and Ran stole a boat to explore the shelter, ignoring dangers like the Acari X virus. After a cave-in, he abandoned a teammate but later cooperated with Hana Sugurono's group to escape.

Following Izayoi's sacrificial death protecting Ran from Ango, Akiwo reconciled with Kurumi's faction. Relocating to Team Spring's flooded base, he participated in a failed hostage exchange involving Momotaro and Koruri. After a bat attack injured his team, they joined Team Summer A. When Hana disappeared and Ango's assault was revealed, he confronted Team Summer A's leadership, aiding in exiling Ango and Ryou. After a forest fire destroyed the camp, he led his team into an uncertain future.
