Keisuke Suga (須賀圭介, Suga Keisuke) is a side character in Weathering With You.
Although he has a kind heart, Suga is deeply troubled by the death of his wife and the seizure of his daughter, which makes him fall into alcoholism and smoking. His struggle to take back Moka's custody also makes him a coward as he quickly fires Hodaka to avoid getting into trouble with the law when approached by the police. However, his grief for his wife also leads him to heroic acts as he empathizes Hodaka's desperation to save Hina Amano.
Unlike his niece, Suga doesn't believe in supernatural stories and only pursues them for money.
Keisuke came from the distinguished family of Sugas, so his parents had super-high expectations for him, yet he was overshadowed by his more brilliant older brother. Like Hodaka Morishima, he ran away from his hometown to Tokyo when he was a teen, where he met and married Asuka Mamiya.
Together they found K&A Planning Co., Ltd. and gave birth to their daughter Moka on March 3, 2016. A few years before 2021, apparently in 2019, his wife passed away in an accident, and her mother took Moka's custody from him.
Natsumi reveals that Suga's parents had high expectation for him, but his older brother (Natsumi's father) was more brilliant.
