Who Still Writes Traditional Diaries These Days?

After transmigrating into a comprehensive anime world, Miyauchi Hiyage obtained a magical diary. As long as he wrote in it daily, he would receive rewards.

However, having read diary-stream webnovels before his transmigration, he knew that whatever he wrote would, with high probability, be seen by the heroines of this world.

As a slacker with no great ambitions, Miyauchi Hiyage immediately decided to be a pure troublemaker in this world.

"What era is this? Who still writes traditional diaries?"

"Surely, no one would actually write their true feelings in a diary only for it to be gawked at by who-knows-how-many heroines, right?"

"My mom told me this world is dangerous. Boys must protect their privacy when they're out and about, so don't even think about coming to find me. After all, I'm the man you'll never get."

As Miyauchi Hiyage continued to write in his diary, an "Avengers-like alliance" composed of heroines who could see his diary quietly formed.

Their sole purpose in gathering was to find the owner of this diary and subject him to inhumane torment!
