Iberis, an S-class esper diagnosed with a terminal illness.
Having lost all his family, colleagues, and loved ones,
He had no attachment left to life.
If he had a wish, it was only to die with a little less pain.
Lucas, a guide who abruptly entered his life,
Began to shake up Iberis’s world at some point.
“I’m sorry, but I can’t bear to see you die, Major.”
“…Why?”
“Because I want you to live. So… open your mouth, quickly.”
Iberis, who has no will to live,
And Lucas, who struggles desperately to save him.
Walking a tightrope between life and death,
What kind of ending will these two face?
