Famitsu (November 14 2019 issue) profiled some of the supporting characters in Ryu ga Gotoku 7, focusing on the main players in the four organisations Kasuga Ichiban will become involved with. No source link, since this is from the print version. You can buy it here, if you want a copy: Bookwalker.

For main character profiles, see here.

OMI RENGO 近江連合

The yakuza organisation that rules Kansai. They took advantage of the betrayal by Arakawa Masumi, formerly of Tojo Kai, to increase their power base, and now Kamurocho is also under their control.

天童陽介 Tendou Yousuke – Voice: 田中美央 Tanaka Miou

Wakagashira-hosa [assistant captain] of Omi Rengo, and patriarch of Ryudou Kai, a top-rank gang in Omi. An Omi Rengo executive who knows he looks good in a three piece suit. He was once a famous pro boxer, but ended up in the yakuza following a scandal.

石尾田礼二 Ishioda Reiji – Voice: 速水奨 Hayami Show

Wakagashira-hosa of Omi Rengo, and patriarch of Ishioda Gumi, a top-rank gang in Omi. Another Omi Rengo executive, who hides the large sword scar on his face with sunglasses. He takes what he wants with physical strength, he’s a warrior yakuza whose words and deeds are always shocking.

安村光雄 Yasumura Mitsuo – Voice: 鶴岡聡 Tsuruoka Satoshi

A wakashu [junior member] of Arakawa Gumi in Omi Rengo. The only one who has a fondness for the Tojo Kai Arakawa Gumi times before Kasuga Ichiban went to prison. Kasuga’s nickname for Yasumura was Mitsu, and the two of them had a strong bond. Now he continues to serve Arakawa Masumi in Arakawa Gumi under Omi Rengo. When Kasuga meets Mitsu after his release from prison, what will happen …!?

荒川真斗 Arakawa Masato – Voice: 鳥海浩輔 Toriumi Kousuke

He has no gang affiliation, but he’s Arakawa Masumi’s only son, who is adored by Kasuga Ichiban. He has to use a wheelchair because he suffered from hypothermia right after his birth. In his daily life he relies on Kasuga Ichiban to act as a kind of manservant, but he also has great trust in the Arakawa Gumi wakagashira Sawashiro Jou.

HANPIN RYUUMAN 横浜流氓 [Yokohama Refugees]

The Chinese mafia organisation who control one area of Isezaki Ijincho. It’s said they make a huge profit from restaurants and import/export businesses, but how they spend that money is unknown.

趙天佑 Cho Tenyuu – Voice 岡本信彦 Okamoto Nobuhiko

[English name: Tianyou Zhao *see update below]

The leader of the Yokohama Refugees, an organisation that prides itself on its fighting, and sees anyone other than its fellows as enemies. He’s friendly enough, but he’s also a schemer whose true feelings are hard to discern. In a fight, he handles his Blue Dragon sword with skill, and his cooking is top-class too. His hideout is in the high end Chinese restaurant Keikin Hanten.

馬渕晶 Mabuchi Akira – Voice: 竹田雅則 Takeda Masanori

The Yokohama Refugees’ advisor and the organisation’s number 2. He manages the import/export business, and his skills provide the organisation with a plentiful supply of cash. He’s extremely ambitious, and in some ways sees Cho as his rival.

YOKOHAMA SEIRYU KAI 横浜星龍会

The yakuza organisation that controls Isezaki Ijincho. Because they’re also part of the “Ijin Three”, neither Tojo Kai nor Omi Rengo can interfere in this area.

星野龍平 Hoshino Ryuhei – Voice: 金尾哲夫 Kanao Tetsuo

The patriarch of Yokohama Seiryu Kai, the only yakuza organisation in Isezaki Ijincho. Valuing honour and the moral code, he is known as a pure “gokudo” who retains the morality of his former civilian life. He’s been the leader of Isezaki Ijincho’s underworld for many years, and he’s a kind of “watchman”, always defending it from invaders.

Yokohama Seiryu Kai headquarters is clearly set up for maximum defence against invaders, making it look a bit like a castle. The building is fortified both inside and out, and if anyone should manage to break in, it’s said that they won’t come out alive.

高部守 Takabe Mamoru – Voice: 遠藤大智 Endou Taichi

Yokohama Seiryu Kai wakagashira [captain], the organisation’s smart and capable number two. He’s pledged loyalty to Ryuhei, who relies on him completely. He has a cold personality, but is also capable of displaying merciless bloodlust when faced with enemies.

コミジュル KOMIJUL

This Korean organisation hangs out in a fort-like building. They’re an enigma. There are electric cables strung all over the place, so they must be stealing a lot of power from the neighbourhood.

ソンヒ Son-hi – Voice: 武田華 Takeda Hana

[English name: Seong-hi *see update below]

The mysterious organisation called “Komijul” lives among the cables in this fort, like spiders in a web. The Isezaki Ijincho inhabitants are afraid of them, though no-one really knows who they are or what they want. But this beautiful woman is their leader.

ハン・ジュンギ Han Jun-gi – Voice: 中村悠一 Nakamura Yuuichi

[English name: Joon-gi Han *see update below]

Komijul advisor, the right hand of the leader Son-hi who supports the organisation with her. On the one hand he’s calm and rational, but as a hitman he has to be able to quietly eliminate people who get in his way, so he’s also ruthless.

So … yes, that is Han Jun-gi. Looking pretty good for someone who took a bullet in the brain three years ago. I was hoping there’d be some explanation in his profile as to what on earth he’s doing here, but nope. Maybe he’s a robot, and that’s why they need all that electricity!

Also, that Mabuchi guy is creepy. He looks like a goblin!

Update: Now these are up on the official site too, I’ve added the official “English” names for the Korean and Chinese characters as listed there. The reason they’re so different from the names I provided is that I used the Japanese readings as listed in Famitsu, while it seems the localised version will use Anglicised versions of the “original” language reading of the Chinese and Korean names. Maybe “Zhao” is actually pronounced “Cho” in Chinese, I don’t know. But I do know that “Cho Tenyuu” is what you’ll hear in the game.
