Published by TO Books [Book Title: The Most Evil Calamity Adventurer Rushes to Help People After Dying Once]

Ryo Asumi, an orphaned high school student abandoned by his parents shortly after birth, is suddenly caught in a hero summoning one day and transferred to another world.

However, while the four others summoned alongside him and made heroes were granted unparalleled skills and magic power, Ryo alone had zero skills and zero magic power, possessing only a mysterious, unidentifiable gift called 'Cycle of Life and Death.'

'Let's all work together, overcome these challenges, and return to our original world!'

Under the hero's encouragement, days of diligent training ensued.

With his innate insight and judgment, Ryo began to turn the tide of battle and save his comrades from danger. Before he knew it, he also started receiving affection from the princess of the kingdom to which he was summoned, but a grave secret was hidden within him.

And when that secret was revealed...

'...So, in the end, I was unwanted in this world too...'

Eliminated, his life taken, and on the verge of his very soul disappearing, his sole gift, 'Cycle of Life and Death,' activated, and he resurrected as the strongest being.

Ryo, now known as Shiryu after changing his name and becoming an adventurer, decides to fulfill a certain promise as his purpose for living and embarks on a journey into the other world, where danger and adventure await.
