Takashi is probably the most excitable member of JINBOU, as well as being the youngest. Dhiar nicknames him "Cockatiel-kun", in reference to his hair.
Later, after the steamy visit to the baths, Takashi becomes more comfortable with himself and with Dhiar, as well as closer to the other members of the band. Because he used to come to the baths with his grandfather, he is reminded of that distant memory by Dhiar's heartfelt warmth.
Takashi later does a solo song entitled "Cockatiel", which deals with his pleasant memories of Dhiar's visit.
