Personality
Knowledgeable and intelligent are the two words that best describe her personality. Sachiko excels her research into developing systems, and new technology for Gunpla units in each of the teams representing their high schools in the Gunpla Grand Prix.

She also has the tendency to be cocky; stubborn; and rude. As she had lashed out at Ash, Jake, and Xavier for flirting with her despite them having girlfriends; resorting to act like a tsundere toward them.
