Seiya Ryuuguuin

Seiya Ryuuguuin is the main protagonist of the The Hero Is Overpowered but Overly Cautious series by Light Tuchihi and Saori Toyota.

Personality
Seiya Ryuuguuin is defined by his overly cautious nature. He refuses to face any enemy he isn't sure that he can beat, will attack defeated enemies repeatedly on the off chance that they can revive themselves, and worries that any stranger he meets could be an enemy or carry a deadly illness, even his own partner.

However, his cautious nature also makes Seiya extremely diligent when it comes to preparing for future battles. He'll grind for levels for days at a time and is almost tireless in his training.

Seiya also tends to speak bluntly to others and is quick to express his dissatisfaction with the opinions and actions of others.

Despite coming off as a guy who doesn't care about anyone, his actions are driven by a want to avoid harm or death coming to those he cares about, even if it means pushing them away.

History
100 years ago, before being summoned to save Gaeabrande, Seiya was summoned by the goddess Aria to save the B-ranked world of Ixphoria. During this time Seiya was very reckless and didn't like to train at all. Even without knowing for sure he'll win and having stats that were clearly lower than the enemies he faced, he still charged in. His companions Princess Tiana (a healer) and Colt (a mage) warned him of his recklessness, but he still pushed ahead and somehow was able to reach and kill the demon lord. However, right when they were celebrating their victory, the demon lord attacked Colt from behind and pierced his chest with his tongue. The lord revealed that it had two lives and the hero only managed to take one before swallowing Ariadoa to regain his strength. Seiya, realizing Tiana and him were in no condition to fight, told Tiana to run away but the demon lord went after her first and revealed that she was carrying Seiya's unborn child. Cruelly, the demon then killed Tiana and the child in front of the him before killing him. Seiya lost all his memories about that world, but the pain and regret of not being able to save his loved ones were deeply carved into his soul.

When Ristarte summoned Seiya to become a hero, he was initially extremely wary of the development and the goddess. When Rista asked him to say Status he instead said Properties and he saw a message from his past self -


 * "Be careful. Be cautious. Be overly cautious. You may find yourself alienated or hated, but you have to endure it all. This time, for sure, you'll prove that you can save your friends, your loved ones, and the entire world."

So he refused to begin his adventure right away and instead trained in his room for days.

When he finally did visit the S-Rank world of Gaeabrande, he immediately bought three sets of armor and items to help him escape from battle. Then he defeated a single slime by repeatedly, and unnecessarily, attacking it with his strongest techniques. However, this ends up drawing the attention of one of the Demon Lord's Four Heavenly Kings, Chaos Machina.

Seiya and Ristarte quickly flee from her and return to the Realm of the Gods. Here, Seiya begins training once again. He returns to Gaeabrande just before Maquina could kill another hostage, the father of a child he encountered earlier, and manages to defeat her augmented form.

After his victory, Seiya begins training with the sword god Cerceus but quickly becomes more powerful than the god. Then he and Ristarte begin exploring more of the world, quickly discovering that a zombie army is approaching another village.
