Recap over
~~~~~~~~~

As Issei woke up the next morning he'd remember he was all alone in the house "what do I do now?, well I guess I have to go to school right?" Issei asked himself still not knowing what to do. Issei thought for some more time and came up with something, he would go around the city exploring the areas he lives around more...

Issei traveled all over the place and managed to discover quite a lot of area, but there was a place that gave him weird vibes. The place that Issei wasn't sure of going to was a shrine that was mostly isolated from the rest of the other homes and towns.

"Hmmm that place seems weird, it gives me chills" Issei murmured.

Issei was walking for around 25-40 minutes while dazed off issei suddenly bumped into someone. The person issei had bumped into was a white haired lady dressed in a maid outfit.

"Please forgive me young man" said the beautiful women, "Oh, no please forgive me I wasn't paying attention, my name is Issei Hy~, just Issei"

"It's a pleasure I meet you Issei my name is Grayfia, let's keep it at that, I must go I'm in a hurry..." Grayfia then took her leave.

(In his head)
Issei: she seemed nice, hey system, could you identify her?

System: Unfortunately that is out of my capabilities, I do not posses her genetic material.

Issei: Hmm very well, I think I should go back into the Quest zone it's time I kept leveling up.

System: as you wish.

Issei arrived at his house and went straight into the Quest zone. Issei was once again in the forest but unlike the other time, Issei had seen a giant black demon wolf with a scar on his face. this wolf was 2 times bigger and many more times stronger, faster and more intelligent than the others Issei faced.

Issei: Inspect!

Issei: Geez, this Wolfe is stronger than me, System how much does Excalibur Rapidly increase my speed?

System: Excalibur Rapidly increases your speed by 300, this is not counting your current speed stats.

Issei: I'm faster, but it's wide variety of skills are a nuisance.

The giant demon wolf stepped forward in a challenging gesture. Issei didn't know what was going on and stood there, the wolf then started walking slowly and eventually picking up speed the wolf was on a full sprint. Issei called out to Excalibur Rapidly. And started battling with it.

The Wolfe slashed dodged, lunged out to bite, and attacked in many various ways. Issei in the other-hand kept dodging with his speed, Issei kept dodged in order to get the beast low on stamina, so that when the time came he'd  be able to easily kill it.

Issei and the alpha demon wolf fought for 12 minutes straight with no rest. "It's more resilient than the other demon wolves, not to mention the other demon wolfs didn't have any ability's that were magic, and this one does." Issei then started to smile very faintly at the wolf who was very tired itself.
