Sign-In at the Fairy Guild, and My Dragon-Slaying Magic Mutated

After transmigrating into Natsu's body, he gained a sign-in System. From the start, he signed in at the Fairy Tail Guild, and his Dragon Slayer Magic mutated.

His mutated six-dimensional attributes can kill anything he encounters!

He signed in at the Magic Council, the temple on Galuna Island, and Deliora.

From then on!

Natsu couldn't stop signing in.

He signed in to get the stars of the Heavenly Wolf Island, and became Fairy Tail's guild master along the way.

He signed in to get demons, and wiped out the Oracion Seis along the way.

The Twelve Shields of Ishgar are all amazing. Every sign-in boosts his strength dramatically.

Zeref is an incredibly powerful guy. Natsu checked in on Tenrou Island and signed in Zeref while he was at it.

What's it like to sign in while standing on Acnologia's head?

Let me tell you!
