Hitomi Nakayama, operating under the online pseudonym Tamasudare, masquerades as an elderly woman within a chat group frequented by Mamoru Suzuhara. Drawing on experience from a parallel conflict three decades earlier, she supports Mamoru during a subsequent crisis by spearheading the search for Malet’s parents.

Residing near Nanyo—a region home to a Thai immigrant community—she harnesses local networks to track down Thai individuals across Japan, ultimately reuniting Malet’s family.

Her dual engagement in past and present iterations of the conflict bridges generational divides through firsthand knowledge and regional ties. Physical attributes include black hair, red eyes, and Japanese nationality, with no explicit references to age.
