a brand of brash agressiveness

角田光代の "The Eighth Day" (原題　八日目の蝉)を読んでいます。
Kiwako was attracted to Takehiro's all-out determination to get ahead. At the time, it was unusual for employees at branches of K Corporation to be transfered to Tokyo. To Kiwako, who had made only the safest choices in every aspect of her life, his brand of brash aggressiveness seemed dynamic. To Takehiko, recently arrived in Tokyo, everything seemed fresh and new; he would take Kiwako out to the cafe-bars and discos that were becoming popular at the time, and Kiwako also found this rather flashy way of spending her free time new and stimulating.
