(Holy Armor: This book is set in a modern Tokyo worldview, involving MyGO, I recommend, Lonely Rock, etc. It is also a harem story with a male protagonist, so please do not read if you don't like it.)

Lu Yu, seventeen years old, is handsome and has excellent character and academic performance.

After traveling to a hodgepodge of Tokyo-style anime, Ruyu obtained a system that can train heroines from various worldviews to become masters in the field of music and help them solve their problems.

Thus, Lu Yu began his journey to become a gold medal mentor.

Hoshino Ai, Toyokawa Shoko, Goto Ichiri...

With Lu Yu's help, one girl after another overcame difficulties and achieved success. However, when the girls became successful and wanted to repay him, he had already hidden his fame and left quietly to go to the next heroine.

"You said I was the best idol in the world, so why did you leave?"

"We agreed to be in a band for life, how could we allow you to escape?"

"I won't let you escape. Even if I have to chase you to the ends of the earth, I will find you!"

Lu Yu: “???”

It's just a system task, don't take it seriously.
