At 16 years old, Asuka Tachibana belongs to HOLY. Despite her friendly disposition when not fighting, she turns serious and professional during conflicts. Initially, a competitive yet unrequited rivalry with Kazuma develops after he humiliates him in an escape attempt from HOLD headquarters and defeats him easily in battle. Later, while both are trapped underground, Asuka gains new understanding of the values held by native Alters through Kazuma's guidance.
