「I say, Mai.
I know that you are strong in your own way.
However, you'll become stronger if you use【body reinforcement magic】.」
「Really!?」
「Yeah, did you not learn【body reinforcement magic】properly?」
「Since there wasn't anyone who could use magic around me......」
「I see, you grew up in a human country. No wonder......
How about this? Would you like me to train you for a while?」
「Er, well. No.
I can't stay here for a long time......」
「I see.」
「I'll come again once I can use【Body reinforcement magic】and becomes stronger.」
「Umu, I'm waiting.」
Mai-san and the previous Demon Lord shook hands tightly.
Rather than grandfather and granddaughter―
this is something like sports.
***
When we left the house of the previous Demon Lord―
we came into a tea shop and have a little rest.
「Captain's fight was amazing~.」
「Yea...」
Mai-san is somehow a little down.
I wonder what's wrong?
At such a time like this, she is not going to cheer up even if she sees a beautiful demonkind onee-san's horn!
「Captain, what's wrong?」
What!
A teardrop from Mai-san's eyes......
「Mai-san, what happened?」
「……
frustrating......」
「What is frustrating?
You've won against the previous Demon Lord...your ojii-san!」
「He was holding back......」
She noticed, huh......
After a while......
When Mai-san raised her face with *ku*―
「I have a favor to ask, onii-san.」
「What is it?」
