Leopin was naturally dexterous.

Utilizing this dexterity, he engaged in various crafts from a young age, contributing to his friends.

Leopin enrolled in the 'Royal Pioneer Academy' with his friends.

However, during the 'Ability Awakening Ritual' at the entrance ceremony, the stats bestowed upon Leopin were disastrous.

'Job: Jobless'

'Stats: All but Dexterity remain at initial values and do not grow'

'Skill: Jack of All Trades, Master of None'

Leopin, who had absolutely no redeeming qualities apart from his dexterity, was 'expelled' by his classmates.

Leopin was placed into a remedial class called the 'Special Training Class'.

Leopin found himself alone.

However, he soon realized that the skill he had been given, 'Jack of All Trades, Master of None,' possessed an unexpected ability.

It was this:

'The Dexterity stat can be converted into other stats'

'Can change jobs to any desired occupation'

Leopin first changed his job to 'Lumberjack' and obtained timber from the forest.

Then, he changed to 'Carpenter' and built a magnificent house, superior to anyone else's.

He changed to 'Appraiser' to identify rare items, then to 'Battle Axe Wielder' to repel students from other classes who had provoked him.

He changed to 'Ranger' to explore dungeons, and to 'Ninja' to effortlessly navigate traps.

Leopin had obtained the power to accomplish anything by himself (solo).

As he continued his unparalleled feats, he gained the admiration of his childhood friend, a Saintess, and was noticed by a beautiful alchemist, further spreading Leopin's renown.

Meanwhile, the classmates who had expelled Leopin witnessed his abilities firsthand and regretted their decision.

Their homes remained mere shacks, their explorations faltered, and they gradually lost their place within the academy, leading to their ruin.
