"Schoolgirl (?) Goes to Another World"

Mahiro, a nerdy high school girl with black hair and black eyes (lol). Her precious childhood friend disappears right before her eyes, and when she comes to, she's somehow been transported to another world too! Swords, summoning magic! Woohoo!!! However, there's the matter of her having become a young boy. Like, seriously...? This is turning into a comedy with that kind of vibe... that's the plan. She won't be overpowered early on, but she'll become reasonably strong at an early stage. Additionally, due to the male transformation, there's a high possibility that BL and spiritually yuri expressions will appear, so please be aware.
