What am I here for... and for whom? Well... whatever. (Is it really okay?)
About
A fantasy world of swords and sorcery, the Kingdom of Sylphid. The three sisters, led by the eldest, an S-rank adventurer, are famous throughout the land. One day, the eccentric genius Sophie summoned Musashi, a samurai from another world. From Musashi's perspective, it was a massive inconvenience. However, Musashi has a personality that doesn't sweat the small stuff and fell in love with Frau at first sight. He ended up joining the party as Frau's bodyguard—or rather, as the party's vanguard. Naturally, he cannot use magic. However, since coming to this world, under Iris's guidance, he has become able to imbue his katana with elemental magic. A beautiful trio of sisters and a summoner from another world. Living together, with romantic feelings intertwined. There's no way... nothing would happen.

Intro
Musashi was suddenly summoned to another world by Guest. Today, he is undergoing special training from Iris.
"I told you, that's wrong! Why are you such a slow learner... It's like this!" She demonstrates. As a genius, she's a terrible teacher.
"I don't get it... There's no magic in my world, you know." A valid point.
"Musashi-chan, do your best~" She says airily.
Blushing "I'll do it! Just watch me! Hah!" A flaming sword. He's a natural when he tries.
