Xi Yue, a boy who has been bedridden for many years due to a terminal illness, arrives in the world of Digimon 01 for unknown reasons.

"Now that we've been given a new lease on life, we should naturally enjoy this new chapter!"

But……

What does "Chosen Children" mean? I have neither the DigiDestiny Plan nor a Digimon—

"Xiaoyue~"

"..."

Looking at the adorable creature staring in their direction, Xi Yue fell into deep thought.

"That... Belstarmon, when did it arrive?"

"Yes, I love you too!"

"Croak~~~"

In short, this is the story of a child who wanted to live a leisurely life but was forced onto a journey to save the world by a series of coincidences.

P.S.: I'm not sure if this counts as a no-female-lead story~ After all, can a Digimon story really be called a female-lead story? (Seriously)
