Matsushige (松重) is a character introduced in Yakuza Kiwami.
He views Nishiki with utter disdain, showing a complete lack of respect towards him, thinking that he'd much rather serve under Kiryu rather than Nishiki.
He wears a navy pinstriped suit over magenta shirt. He has a short curly hair and a stubble and wears a pair of aviator sunglasses.
Following the formation of the Nishikiyama Family, Matsushige is transferred over to the family from the Kazama Family under Osamu Kashiwagi's order to help the family get on its feet, as Matsushige is known to be a top earner in the Kazama Family. However, Matsushige is less than pleased working with Akira Nishikiyama, viewing him as someone who only got his position through his connections.
One day, Nishikiyama is desperate to raise funds to pay for his sister's heart surgery. A doctor is willing to help as long as Nishikiyama paid him 30 million yen, causing Nishikiyama to beg and grovel for Matsushige's assistance to get the said 30 million yen. Much to Nishikiyama's anger, Matsushige earned it by intruding in Kashiwagi's territory, as he was told to earn the money in any way possible. Matsushige was eventually able to help Nishikiyama reach the 30 million goal by a debt-ridden doctor who was suddenly able to produce enough money to pay everything back; the doctor in question being Dr. Kiminobu Hiyoshi, who was supposed to save Nishikiyama's sister.
After Yuko's passing, Matsushige enters the room of a currently-mourning Nishikiyama about to commit seppuku and asks for permission to expand business, but further insults him by calling him inept and comparing him to Kiryu when he does not get a response, causing Nishikiyama to stab Matsushige instead, killing him.
