Who is that guy?

Kiku wasn't sure when it had started, for all he knew it could have been going on for some time without him noticing. But one day he realised there was a man sleeping by his window. Now, as one of his majesty's wizards Kiku had the perk of living in one of the castle towers. Which meant that his windows had a lovely little perch which he had filed with pillows and blankets so that he could relax there when he was having his evening tea. But this afternoon he realised that it would be rather hard to follow through unless the man in question didn't move away.

He spent another hour politely waiting for the man to wake up by himself. When this didn't seem to work he took a deep breath. And went over to gently shake him awake. Oh boy, he was rather large. Not only was he like most people taller than Kiku but he was also rather muscular .Kiku didn't want to make him angry.
"Excuse me. Sir. Would you please wake up?"
This proved to be.. utterly useless. The man didn't even stir. When Kiku tried to use more force, he snored. Kiku's hands shock as he took to his last resort. This was highly impolite, but it was necessary. He took the biggest spoon he owned and slammed it into his empty cauldron making it chime like a big bell. Now, finally the man slowly opened a bleary eye.
"Is it dinner?" He asked.
"No sir. May I ask, what are you doing in my chamber?" Kiku asked shyly. The man took a moment as if he had to really contemplate the answer.
"Sleeping." He answered indifferently. Kiku took a deep breath through his nose.
"But, don't you have a room of your own where you could do that?" He asked. Again the man seemed to contemplate this.
"That I have." He answered.
"I don't mean to sound rude but why don't you sleep there?" Kiku asked with a certain measure of confusement.
"... Don't want to. Besides, it is comfortable here."
Now it was Kiku who stood quiet to contemplate how to answer. What did it actually harm that he slept here? Maybe he had troubles at home he wanted to escape by coming here?
He was just about to declare his decision of letting him stay when he realised the man had fallen asleep again.

The following days he realised the man had made a habit of sleeping in his window. Every day he would come in without Kiku noticing and nap among the pillows for hours. Occasionally, since Kiku had initiated contact, he would wake up and talk to Kiku. Mostly about small extremely random and seemingly unimportant things (such as the pros and cons of wool socks). Kiku also noticed that the man seemed to attract large amounts cats. Every day there would be a new one in his chambers, usually cuddling with his "guest". He didn't mind. As long as they didn't disturbed his works (which in all honesty when they did, he overlooked it). He liked cats. And just like that, the man in the window, who on the third day introduced himself as Herakles, grew on him.

However there was occasions when he still considered to politely ask Herakles to leave. This was one of those days. He was supposed to try out a new spell, a tricky one, and for that he would have liked to be alone. Not that Herakles company harmed in any way, he was currently dozing off with a cat by his side. Then suddenly, just as Kiku added another line to the spell work he was drawing on the floor Herakles suddenly flew from his resting place with catlike agility, moving faster than any man Kiku had ever seen. He lifted Kiku away from the pattern and cowered him with his arm while facing the spell work.
"Wha..!" Kiku squeaked before a massive amount of magic energy rose from the pattern. It was like a living being, but made solely from magic. And Herakles stood now in it's way.
"Move! Let me..!" Kiku shouted terrified but Herakles just stretched out his hand towards the being. What happened next looked the most to Kiku like Herakles just pressed the being back down into the pattern. Once the magic seemed to have settled Herakles proceeded to wipe away the pattern from the floor.
"Who are you? What are you?"Kiku whispered breathless.

Herakles gave him a worried glance before lifting Kiku up again and carrying him (under flustered protests) to the window. He then simply settled him down and laid a cat in his lap.
"When working with magic, one need helpers. Beings who works in the magic itself. You need to know these helpers very well, and trust them like your own hand." Herakles spoke. Though it was more than he usually spoke he seemed to be fumbling for words. Kiku tried to make sense of it when Herakles finally looked him straight the eyes. His olive green eyes seemed to shine with an ethereal light.
"You have never trusted me." Herakles stated without any tone of accusation.

"You are my helper?"Kiku asked. "I didn't even know you existed."
"You never noticed me." Herakles stated calmly.
"But, you are here. In physical form?" Kiku asked confused. Shouldn't he be more like the being that just had disappeared through his floor?
"You need to see me. Learn to know me, trust me." Herakles said suddenly putting weight on his words. Kiku suddenly felt like crying. His helper had been forced to take physical form, because he had been blind and not noticed him. But as if feeling Kiku`s distress Herakles placed his hands over Kiku's.
"You are going to be a great wizard." He said so convincingly Kiku almost believed in him. And then he smiled. The first smile Kiku saw from his otherwise tired face. And he couldn't help but smile back.
