SII Riou Portrait.png

"Everyone, lend me your strength!"

Riou is a recurring character in the Suikoden series. He is the hero in Suikoden II, and is the silent protagonist and Tenkai Star of that game. He also makes cameo appearances in both Genso Suikogaiden Vol. 1 and Genso Suikogaiden Vol. 2.



Riou is a soldier of the Highland Army's Unicorn Youth Brigade and 16 years old at the beginning of Suikoden II. He wields a tonfa and becomes the bearer of the Bright Shield Rune.


Riou is a young man with short brown hair (black in his in-game sprite appearance) with fringes on both sides and two upward fringes is in the center of his head. He wears a red and white sleeveless Chinese garb with a yellow scarf on his neck and a light blue obi that tucks on his garb, black capris and brown battle boots. He also wears a circlet on his forehead and wears light blue and brown gloves. His weapon of choice is a pair of Tonfas.

As a child during flashbacks, Riou wore a red long sleeve Chinese garb, black capris and sandals. This appearance will be seen again which was now worn by Ko from Banner Village.


Like Tir McDohl in the first Suikoden, Riou is also an outright, rebellious, calm and serious person, and he is determined to fight against Highland as the leader of the Allied Army. He cares for his step-sister, Nanami, as well as his best friend, Jowy. Nanami keeps telling Riou to give up on his fight as New State Army leader because she claimed that she doesn't want to see Riou and Jowy fighting each other.

During the conflict in the Dunan Unification War, Riou didn't want to stop fighting against his enemies but having conflicts with his best friend, Jowy, due to their destiny with their true runes that attached in their right hands. When Gorudo and his men fatally injures his step-sister, Riou shows his anger towards them and also shows his grief when his step-sister faints due to her fatal injuries sustained by them.

In the best ending, after constantly refusing to fight Jowy in a duel to the death, Riou heals Jowy back to health using the power of the Bright Shield Rune. If Jowy dies, he becomes the bearer of the Rune of Beginning as a whole.

He also befriends Tir after they team up in defeating the Poison Moth with their combined true runes as well as their unite attacks that proves them more powerful. They also share their role as the silent protagonist.

In the manga, Riou is a big-eater, for him every food is good, he likes to daydream and never prejudices anyone.


As a child, Riou had been left as an orphan by wars and he and Nanami were adopted by a hero named Genkaku. He grew up in a small Highland town called Kyaro, and eventually became friends with Jowy Atreides. Along with Nanami, they would train under Genkaku to become strong fighters. Riou and Jowy went on to join the Unicorn Youth Brigade.

When the Youth Brigade was slaughtered by Luca Blight as an instigator for war, Riou ended up separated from Jowy and was captured by a band of mercenaries under the command of Viktor. Jowy attempted to rescue him after ending up in Toto Village by sneaking into the Mercenary Fortress, but the boys were both caught. After several attempts, they managed to finally escape and reached their hometown, Kyaro, where they reunited with Nanami. Their reunion was fleeting as Riou and Jowy were arrested soon afterwards by their former captain Rowd. They were rescued by Viktor and Flik, and the boys and Nanami escaped from Highland and aided Viktor by recruiting more mercenaries.

During the Dunan Unification War, Riou and Jowy were approached by the strategist Apple, who intended to approach Viktor and provide him information concerning the plans of the Highland Kingdom. After recruiting Tsai and witnessing the insanity of Luca Blight, Riou and Jowy joined the New State Army. After Jowy assassinated Lady Anabelle at Muse, and left the New State Army to join the Highland Army, Riou, Nanami and Pilika escaped to South Window via Coronet where they meet again with Eilie, Rina and Bolgan.

Following the defeat of Abomination, the former North Window Castle became Dunan Castle and officially turned out as a base of operation for the New State Army. Riou became the leader of the New State Army after defeating Solon Jhee. He soon found that he had no other choice than to fight against Jowy after he married Jillia Blight and became de facto the Commander-in-Chief of the Highland Kingdom's army. Both young men ended up inheriting half of the Rune of Beginning, and must end the war before their friendship is torn apart forever.

In the middle of the game playthrough you could attain an immediate ending:

  • Coward ending: Agree with Nanami's advice to abandon everything he had fought for and live a peaceful life away from the war.

Post-Dunan Unification War

Depending on the ending and/or the player's choice:

  • Alternate ending: The player chooses to fight Jowy and defeats him. Jowy dies and Riou becomes the bearer of the Rune of Beginning.
  • Country (good) ending: The player says yes when Shu asks him to become the Dunan Republic's President. In the credits an image of Jowy waiting by the falls will be shown indicating there is a battle still left unfinished.
  • Canon (best) ending: Lose in the battle between Jowy at the Tenzan Pass and the Bright Shield Rune will heal him. Shu meets up with you and tells you Nanami is alive. Riou and Jowy will then reunite with Nanami in Kyaro and travel the world.

Role in the Game

As the main protagonist of Suikoden II, Riou is recruited at the beginning of the game, and cannot be removed from the party.

Riou is a fantastic character with above average stats in all categories. He has several powerful Unite Attacks in the game and his Bright Shield Rune is one of the most powerful and useful runes in the game with its diverse functions as both an offensive and defensive rune. A close inspection of his stats show that Riou's stats favor melee stats, but his well-rounded affinity and extra rune slots make him quite diverse for player customization.

  • Head - Gained at Lv. 40
  • Right Hand - Bright Shield Rune (Permanent, Story Event)
  • Left Hand - Gained at Lv. 25
  • Weapon - No rune attached.

Riou has all-around great stats and can be customized for magic or melee. For a melee set-up, a combination of a Double Beat Rune, Double Strike Rune, Killer Rune, or even a Fury Rune will work wonders for him. For a mage set-up, Riou is one of the few characters who can equip a Blue Gate Rune, and he has a high affinity with the Resurrection Rune. The Bright Shield Rune is literally all the party needs for healing although the Forgiver Sign spell is a powerful damaging move too. Riou is a perfect candidate for the Friendship Rune to be embedded on his weapon. Attaching a Fire Sealing Rune to him is very useful in the battle against Luca Blight, because the attack of Luca Blight usually uses the element of fire. If the player has a lot of potch, the player can embed a Technique Rune for Riou.

Riou is an Infantry Unit with 8 ATK 9 DEF.

Unlike other characters seen with soldiers with swords and bows or cast magic, Riou fights his opponents with his tonfas. Starting from the third war, he can use the Bright Shield Rune, which heals all of his allies in a cross formation once. When his unit is joined a character having the Cavalry ability, Riou is seen riding a white horse to fight the soldiers.

Since Riou is the main protagonist, the game ends in a game over if he gets defeated, prompting the player to restart/reload the game.
