Shirou is in fact a light sleeper, a habit he got from cohabitation with his partner back in clock tower.

Rin is not a morning person, and someone need to prepared breakfast.

A habit he brought to this dimension, and it was this habit that dragged him into a trouble.

It was about midnight when Shirou suddenly awake.

He was awaken by a noise coming from the room.

Opening his eyes he saw Harry and Ronald walking away from their bed in school uniform, and heading towards their room door.

Curious Shirou started following them silently.

Shirou saw them in the common room arguing with Hermione about going out late and breaking the curfew. While Harry and Ronald claimed they doing it for the pride and dignity of the Gryffindors. From their explanation it seems after flying class Harry was challenged to a duel from student in house slytherin, needless to say he agree with Ronald coming with him as a second.

Sigh, kids. They're so easy to provoke, but, it does worried Shirou. From what he knew, most Slytherin is came from a magical family with a long history and respected lineage, basically they're nobles. And Harry is supposed to duel them? Harry who claimed to be born and raised in ordinary household where he didn't know about magic until recently and he will duel a Slytherin member who, as far as Shirou concerned, trained from the moment they walked in magic.

That doesn't seem fair.

And so Shirou revealed himself to the arguing trio, surprising them.

"Shirou!" The trio shout, surprise filled their face, in Hermione face hope was seen instead.

When school started Shirou was quick to assert himself to be the 'mature' and 'dependable' one among his classmates, helping anyone who needed or asked for help.

"Shirou! These guys were planning to..." her next word was stopped by his response.

"So I've heard." Shirou simply replied, before looking at Harry.

"Harry the Slytherin is filled with people who might have been trained in Magical arts long before school, dueling with one of then might end in disaster for you." Shirou said hoping for Harry to reconsider. For his credit Harry seem to thought about it before replying.

"I know, but I can't let Draco get away with insulting our house, Shirou." Harry said with conviction, making Shirou sighed and Hermione silent.

"I see, well I can't let you go knowing you might be in danger..." Shirou said making Harry and Ronald anxious, and Hermione is worried if violence happened due to her meddling.

"So I'll come with you." Shirou said surprising the trio, Ms. Granger even gape in shocked.

"WHAT??!"

The shriek was coming from Ms. Granger alone, while the boys were elated.

"WHY?" Asked Ms. Granger, the other two also curious.

"Well, I cant stop you guys from going, but if I didn't do anything you might hurt yourselves, I cant allow that as well, so I might as well come with you, to make sure you're safe," Shirou simply said.

"And besides when it come to a fight I'm confidence to get an upper hand against anyone." He finished reassuring the trio, after all against a veteran magi surely he could knock a child or two in a fight.

As soon as the thought come to his mind, a feeling of shame replaced it.

'Oh how the mighty have fallen, to think a 27 years old adult would get involved in childish quarrel.' Shirou thought before looking at the trio, Harry and Ronald looked elated but Hermione looked as if she swallowed a lemon.

He'll apologize to her later.

So the quadruple left to the trophy room.

Quadruple? You ask, due to her inability to stop them from going Hermione decided to come with them for making sure they didn't get into trouble or something like that.

Wow, even children is saying that to him now, Shirou could feel his confidence as an adult falling.

After some sneaking around they finally arrived on the trophy room.

TheTrophy Roomwas a room that moved between the third and sixth-floors ofHogwarts Castle. This room was used to store all the old awards, trophies, statues, cups, plates, shields, and medals were kept in crystal display cases.

The crystal trophy cases glimmered where the moonlight caught them. Cups, shields, plates, and statues winked silver and gold in the darkness.

But other than trophy and other medals, the room was strangely empty. With no one on the room, other than them.

Thinking that the Slytherin were just late, the quadruple waited. Until they heard a walking step going near the room, surprise they goes to hide around the room. When the door was open they saw Mr. Filch going inside.

At this point Shirou realized that they were fooled and was set up for a trap, looking at the faces ot the trio it seems they figure it out as well.

Mr. Filch started to searching the room, the group waited in their hiding place until the man goes towards another section of the room before they run out of there.

Unfortunately, one of them accidentally makes a noise on the way out alerting Mr. Filch.

"Aha! I know one of you brats was hiding here," The man said in delight.

"When I caught you, I'll make you regret it!" The man said while trying to catch up with then.

Seeing the man chasing them Hermione quickly opened a random door to hide.

"Quick, hide here." Hermione called out to the rest of them, Shirou and the other swiftly followed her. When she closed the door, she breathed in relief before turning around.

Only to see a giant dog with three head looking at them with fangs like shredder ready to maul them.

It was a fucking Cerberus.

Seeing this sight the kids doing the next best thing they know.

Scream.

"Quick, get out!" Shirou screamed while opening the door.

The kids quickly squeeze themselves out.

Seeing the intruder is about to escape the cerberus leap towards them.

Luckily, by the time it leap the kids is already out of the room while Shirou closed the door before dodging out of the way. The cerberus on the other hand slammed the wall hard.

Seeing the creature turned its multiple head towards him with a snarl, Shirou prepared himself for a fight, with summoning Kanshou and Bakuya on his hand.

But not before cursing his luck.

Damn his E rank luck!!

The trio managed to escape successfully.

Their current mood however weren't much to say.

"WE HAVE TO GO BACK!" Ronald screamed.

"ARE YOU CRAZY!??" Hermione screamed back.

"WE CANT JUST LEAVE HIM!!" Ronald claimed, silencing Hermione.

"That's not what I mean...I...I..." Hermione mumbled.

"Guys!" Harry suddenly called, as he remembered something or someone.

"Mr. Filch...he was...over there..." Harry said silencing them, while they process his word.

Hermione was the first to move.

"Mr. Filch! Mr. Filch! We need your help!!" She screamed for help as the boys followed behind her.

Argus Filch would have never expected this tonight.

While this happen, Shirou who is facing the cerberus is in trouble.

Shirou slide himself under the cerberus while slashing its left front leg before standing behind the monster as it howl in pain.

The wound leave a trail of thin blood flowing from it and...

That's it.

It seems in this world the Phantasm beast share the same physical resistance like his previous world.

Meaning a normal weapon or attack won't do any meaningful damage to them.

Thankfully he had Kanshou and Bakuya who have a anti-monster property to them, allowing Shirou to bypass a monster physical resistance.

In fact, Shirou could killed it without much of a problem.

Except, Shirou have one little mishap that stopping him from doing so.

He is currently 11 years old PHYSICALLY.

So all his strike only amount to an 11 years old hitting a beast with a sword, basically not worth anything.

So Shirou have the tool, but was not able to use it properly due to reasons outside of his control. At this point he didn't know who to blame anymore his E-Rank luck or Zeltrech for sending him here.

'Damn it.'

Shirou side step to the right as a paw trying to crush him the edge of his uniform is caught in the attack however, before bending backwards to avoid a claw swipe, crossing his sword he make a cross slash drawing another howl of pain from it.

Shirou step back a few steps to see the damage, only to saw just like before a small wound with a thin blood flow from it.

Shirou squinted his eyes at the sight, his 11 years old body can't keep up with the beast without a much needed muscle power even with Reinforcement. Which he didn't have as an 11 years old, having deduced this he dismissed Bakuya from his left hand and grasp his wand hidden in its holster. A small light coming out of the wand as he grasp it with his hand before dissipating, at the same time some sort of foreign power suddenly coming inside of Shirou empowering him.

Looking at the wand in his hand for a moment, he then turned his attention back into the beast. The power flowed in him was not malicious for the moment so he will focus at the beast in front of him. Pointing the wand at the beast Shirou wave his wand before calling out a spell chant.

"Incendio!"

Fire coming out of Shirou wand towards the beast.
