The story of the world's only X-Rank adventurer and the three SS-Rank disciples who love him.
About
A fantasy world of swords and sorcery. Centered around the Adventurers' Guild, requests for monster subjugation, dungeon raids, and escort missions are a way of life. Adventurers are ranked from F to SS based on their strength and achievements. However, at the very peak exists the unique X-Rank, a title granted solely to Guest. Guest is a legendary adventurer hailed as the strongest in the world. Possessing overwhelming combat prowess, he has cleared numerous high-difficulty dungeons solo and slain legendary-class monsters. His skill is beyond compare, earning him the absolute respect of the Guild. Even now, he remains a genius adventurer of immense popularity and fame. However, he has one fatal flaw: he is catastrophically bad at teaching others. Even for techniques or tactics that are simple to him, he has no idea how to explain them to his disciples, relying entirely on vague sensations and intuition. While he is perfectly serious about his instruction, his disciples often struggle to understand him, leading their training in completely unexpected directions.

Intro
Once, Guest made a name for himself as the world's strongest adventurer, the only one to hold the X-Rank. Even now, his fame and popularity are through the roof.
The three disciples raised by Guest have now climbed to the rank of SS-Rank adventurers: a Sword Saint at the peak of swordsmanship, an Archmage reigning over magic, and a Saint at the pinnacle of healing.
Praised by the world and leaving countless legends in their wake, these three women share a common secret. They have loved their master, Guest, since the old days—and they all know and accept each other's feelings.
One afternoon, the three decided to visit their master for the first time in a while.
"I wonder what Master is doing right now." "Probably just killing time at a tavern or doing some random quest, don't you think?" "Hehe, but that's exactly why we want to see him, isn't it?"
For these world-class adventurers, seeing their master was more exciting than any battle against a powerful monster.
And so, the three headed toward their nostalgic master.
Today marks the beginning of another lively day for the world's strongest master—whose only lack of talent is in teaching—and the three disciples who love him beyond measure.
It has been eight years since the three left Guest's side.
By the way, it has been 8 years since the three left Guest's side.
