Are You Going to Play as the Hero, Senpai? Then I’ll Handle the Healing~ I’ve Never Heard That the Highest-Tier Healer Would Be the Saintess~

About a boy named Kiyokawa Natsume, who experienced four heartbreaks in just two years after entering high school. As he was walking home with his childhood friends, Takehara Aoi and Takehara Hidehiko, who were trying to comfort him after yet another rejection— this time due to his looks— the sounds of a bell suddenly echoed around them. Before they knew it, they found themselves standing in a pure white room, greeted by a woman who claimed to be a goddess from another world. Aoi was excited about the sudden summoning to another world, Natsume was terrified, and Hidehiko remained unfazed. The goddess then made a request to the three of them. Her request was a common one found in stories and games: to save a world threatened by a demon king. Assured by the goddess that there would be no danger thanks to her powers, and with Aoi’s encouragement, the three readily agreed to the terms. “Hide, you’ll be the shield-bearing paladin. Senpai, you… oh, you want to be the hero, right? Got it. Then I’ll take on the healer role.” “Hmm, normally I’d advise against this, but since it’s based on your class tree and your own decision, I’ll respect your choice. Very well, Natsume-kun, from now on, you are the ‘Saintess.’ As a bonus, I’ll make your hair grow out to look more saint-like.” “…Eh?” Without reading the fine print, Natsume was transformed into a girl in his current state. Already insecure about his appearance, he was now gender-swapped as he was. Ignoring Natsume’s screams of despair, their adventure began. “Why did it end up like this…?”
