Takumi becomes possessed during parts of the story, while possessed his voice becomes dark and seething. 

Constantly overshadowed by the talents of his older siblings, Takumi is thus, understandably, sometimes portrayed in a state of moody malcontent due to having developed a bit of an inferiority complex that he covers up, keenly desiring to receive recognition without being framed by the achievements of Ryoma and Hinoka. This fact alone serves as a strength and a flaw; on one hand, this has spurred Takumi to be immensely diligent in his austere efforts to upgrade his abilities, which have made him a very skilled archer. This fact is evident in his supports with Mozu, where he disproves her doubts over his farming capabilities by tirelessly engaging in manual labor on the field.
