Suguru Kouda

As the firstborn of the Kouda family, he fell into a gloomy and neurotic state following his failure in university entrance examinations, spending prolonged periods shut indoors studying and casting a tense shadow over the household. He stands as the sole voice of common sense among his family members, and ever since the bizarre bird Kuzma forced its way into their lives, he has taken to observing the chaos around him with a composed yet sardonic eye—delivering pointed retorts at the surreal antics of both his relatives and the peculiar creature, thereby serving as the story's grounded, reality-check presence.
