Yoko is generally upbeat and boisterous. She will express her opinion without scruples and hates being wrong about anything. Her perfectionist side causes her and her Buddyroid to bicker quite a bit. While she can be impetuous, she is secretly sad inside due to the loss of her parents and is quite sensitive. She initially had a strong dislike for Hiromu, even giving him the insulting nickname "siscon." She warms up to him over the course of the series.
Buster Power Program VaccineEdit
The three primary Go-Busters had program chips installed into their bodies prior to the start of the series that protected them from the dangerous effects of Meta-Viruses as well as cybernetic teleportation. This way, they could be evacuated from the site of the Messiah Incident. The Chips give each Buster a special power to use in combat, typically with a crippling trade-off each Buster must keep managed.
Yoko is granted high mobility and jumping power due to the Vaccine. She can jump to incredible heights; and her nimble frame makes her a perfect scout during missions. Her weakness is systematic. Yoko's body runs on something of an "internal battery," and relies on sweets and other sugar sources to maintain. Should this source should deplete, her entire body will be paralyzed and will cause her to collapse until she is re-energized.
Buddy Roid SystemEdit
Each Buster is assigned a Buddy Roid, which essentially acts as a personal support unit, an interactive console for the Buster Machines, and armor plating for Powered Custom Mode. The Roids have watched over the Busters since the Messiah Incident and as such act as surrogate parents/companions.
Yoko is linked to the Buddy Roid Usada Lettuce.
