Izaya had to get used of this Gennin life of D-rank Missions. At least this one was willing to pay a good reward, different from the other D-rank missions Izaya had to do. The cat of a noble family from the village escaped from his home and is lost around the village, it was seen by multiple people, and Izaya was chosen to bring the cat back to his family.
-Izaya don't hurt the cat no matter what, he is a really important part of their family. Good luck.
Said the Chief of the Mission department of the village. Izaya after listen to all the instructions jumped from the window and headed out of the building.

Izaya went to the last time the cat was seen, the graveyard, but apparently the cat wasn't there. Izaya went up to a old man that was sitting in a bench by himself.
-Hello sir, did you see a long haired cat walking around here? I'm in a mission and I need to find this cat.
The old man looked at Izaya and after a couple seconds he answered him.
-Ohhh so you should be a shinobi right?
Says the old man to Izaya, not answering the question and making Izaya really mad.
-Please sir help me here, did you see a cat here?
-Ohhhh yesss, he was playing around that tree but he went that way, into the woods.

-Thank you sir..
After Izaya thanked the old man he turned to the woods and start running as fast as he could, focusing all his chakra in his legs, trying to increase his speed.
Izaya was running for about 5 minutes in the woods already when he felt a different presence, he hides himself over a tree and look down, there was the cat.

"Alright there is the cat, this should be easy"
Izaya underestimating the cat jump from the tree trying to lay right on top of the cat, trying to catch him without hurting the cat. surprisingly the cat jumped to the side dodging Izaya's move  and scratched his arm after running away.
"What the hell?? That was humiliating, luckily nobody saw that"
Izaya get up and start looking for the cat again. It doesn't take him too long to find the cat, Izaya not wanting to play around use his jutsu, Shunshin no Jutsu (Body Flicker Technique), and appear right next to the cat with an incredible speed, grabing the cat as soon as he could.
-Gotcha you!
But the cat was not playing around, the cat bites Izaya's arm with all his stenght and Izaya throw the cat up, the cat land on a tall acorn tree. Izaya look up to the cat, he was really mad.
-Get down right now!
Yells Izaya to the cat, that totally ignores Izaya and start throwing acorns off the tree right on Izaya's face, making him incredible mad.
-Alright I'm done with you! Don't you realize that you are stuck in the tree and I'm the only one who can help you right now, I'm just trying to help you!
Izaya screams to the cat, looking like an idiot talking to an animal. But the cat starts to realize that he actually is stuck in the tree, and decides to cooperate with Izaya. The cat stop throwing stuff at Izaya, that carefully climbs the tree and catches the cat.
-Alright now lets go back to your house.
Izaya take the cat with him back to the little girl's family, making all of them happy again.
