Mart x Tetra

* Story
One story, while I,Tetra, was exploring a dungeon,
I stumbled across the former demon lordess Mart.
I thought I was screwed. but...she then said:
"I'll make you an adventurer, and together with me, we'll take down the current demon lord!"

Though I've always been weak, I've dreamed of becoming an adventurer,
so I'm taken in by her sweet words, and join her.
So it's me, who can't fight but can store magical energy, and the former demon lordess,
who can fight but can't store any magical energy.
Together. can we defeat the current demon lord?
