Ryuuji Kawara (華原 隆司) is Ryouta Kawara's father and Souma Isa's's research colleague from the Biology Division of the St. Pigeonation's labs.

Ryuuji is a friendly bird with boundless energy and optimism. Despite his happy-go-lucky behavior, his instincts guide to him amazing results.

According to Shuu, Ryuuji was one of the most gifted researchers and the only bird Shuu ever respected. It's been noted that the tie Shuu wears is similar in design to Ryuuji's.

His story is shown in the ending of the Hurtful Boyfriend route. He is also shown in Holiday Star.

Hatoful Boyfriend

Bad Boy’s Love (Hurtful Boyfriend)

Ryuuji is very friendly towards Isa Souma (Shuu's previous name) and often talks to young Souma about his research, his family, or invites Souma out, and so Souma has some strong feelings of attachment to him. However Ryuuji's son, Ryouta, is not close with him, because his father was always busy with research and would only show up rarely.

Ryuuji caught a disease while on a trip, and wasted away from this disease that had taken many other lives. Before he died, Ryuuji asked Shuu for a favour. He asked Shuu to do something for Ryouta if Shuu happened to meet him, because he felt had not given as much attention to Ryouta as he would have wanted. This request was the origin for the events of the Hurtful Boyfriend route. Ryuuji's death greatly affected Shuu, who withdrew into apathetic sociopathy.
