I am a transmigrator who was "destined" to become the strongest deity.
(Though it seems I'm always just destined to be one.)
And it looks like I might not even be able to keep myself alive, since without faith, I'll "starve to death"...
To stay alive, she has no choice but to pretend to be her own saintess, running around all day and exhausting herself helping others, all for the sake of living one second longer.
"Today... I spent 24 hours and got 25 hours of life in return... Great, I get to live one more hour..."
After finally tricking someone into becoming her actual saintess, she discovers that helping this saintess seems to earn her even more faith?
It starts with helping her improve her strength, then holding hands and going shopping... Wait, something's not quite right here.
When did my saintess secret identity get exposed?!
"My goddess, if you still want to borrow my power this month... you'll have to pay back the interest you owe me."
"You don't have it? Then put yourself up as collateral!!"
