Kiyoshi Hasegawa

Kiyoshi is Teru's best friend and a classmate, as well as scholarship student. He attempted to find out more regarding why Teru was left so impoverished after her brother's death, despite Souichirou's reputation as a brilliant engineer. However, he ended up endangering both himself and Teru, until he is saved by Kurosaki. An intelligent boy who is able to exercise discretion, the Master reveals to Kiyoshi DAISY's true identity as a gesture of trust. Afterwards, Kurosaki employs Kiyoshi as a second "servant" and another set of eyes to protect Teru, though Kiyoshi does not hesitate to poke fun at Kurosaki's affection for Teru. (Source: Wikipedia)
