[Single female lead][Fairy Tail][No system][Semi-invincible][Main storyline][Daily life][Celestial Spirit form][Demon form][Azure Dragon form]
A struggling graduate student stayed up all night writing his thesis. Just after saving it, he went out for a late-night snack because he was hungry, and was unexpectedly transported to the Fairy Tail world by a lucky accident.
The goddess bestowed upon him powerful healing (life) magic, allowing Sunrise to live a new life in the Fairy Tail world.
You think healing mages only know how to heal people?
Riyao has proven with its actions that the doctor who can cure you is also capable of beating you up again.
This is Fairy Tail, a place where there are endless arguments, endless drinking, and adventures that never stop.
And a seemingly carefree but actually meticulous healing mage.
He will heal you.
Then I'll beat you up.

Harpy: "Aye! There are also delicious black-backed bass in his pond."
Lucy: "How can I get back the dark history that Riyao has?"
Gray: "Damn it, I can't beat them in a fight, and they've already filmed a bunch of embarrassing things about me."
Mirajane: "My darling is absolutely amazing!"
Lisana: "My sister and brother-in-law are always showing off their love, it's so overwhelming."
Erza: "If only Sunlight could be serious."
Juvia: "Hehehe, Lord Sunshine is such a good person! Do you still have a picture of Lord Gray?"
Wendy: "Mr. Sunshine is so smart, I want to learn magic from him."
Xia Lulu: "A cunning, blond man."
