- Description from novelbuddy

Sakimori Kagami plays a VRMMORPG called Arch Earth Online. He is a veteran player with the name and appearance similar to an elderly bearded wizard from a certain book about a ring.

One day he purchases an appearance change item as a last resort to spend expiring currency and gets the idea of choosing what he would want to look like if his character was ever a girl.

Falling asleep should have suspended the game, but Kagami wakes up still online and feels the game has has gotten a bit more realistic. Did Arch Earth Online finally get a long-awaited update?

“What?! I turn into a little cat… at the end of the world?”

Kate looked at her small limbs with desperation. She glanced at the others who awakened strange and powerful abilities while she turned into a small cat without any combat ability.

She wanted to cry.

Thankfully, this small cat has an owner. Her strict professor who looked cold and unfeeling.

With no other choice, Kate can only follow him.

…

Kyle looked at the little cat in his arm who showed an innocent look.

Have you ever seen a cat acting coquettish after stealing food to hide her guilt?

Have you ever seen a cat take a bath so happily?

Have you ever seen a cat… turning into a little kid?

.....

Looking at the cat eared little girl with cute tail, Kyle sighed and decided to become the girl’s father and taught her the way of the world.

But when cat eared little girl suddenly grew up into an adult… Kyle fell silent.

After waking up in the body of the Young Master of the Luo family, he finds he has the knowledge of hundreds of games and Light Novels. However, he finds his Dantian is crippled, so he can’t practice cultivation! Luckily, he has the Upgrade system.
