And so, every night, the four Valkyrie served their Rider, roaming the halls each night, searching for the presence of the Dementors in Hogwarts. However, Harry and the rest were forced to face something else one morning, their fears.

"Harry! Ron! Takuya! Wake up; we have our first lesson with Lupin today!" Harry woke up to see Hermione throwing a pillow at him. Quickly, a hand shot up and he caught it in his claws. "Ok Hermione, I'm up!" Harry swung his feet out of bed and loped to his trunk, pulling out a school robe. He threw some shoes on and then walked out the door, Takuya waking up as he did so.

"So how much time do we have Hermione?" Harry asked when the group had met up in the common room.

"We need to go to the classroom now; if we do we'll be able to make it just in time." With that, the group set off toward the Defense against the Dark Arts classroom. When they got there, Professor Lupin had told everyone to put away their books and follow him. The worn down professor led them to the staff room and told them they would be facing a Boggart. After Hermione gave her answers and Neville turned the creature into Snape dressed like his grandmother, it was time for the rest of the class.

FLASH, Ron stood in front of the Boggart and it turned into a spider. When he yelled the chant, Reddiculus, it had on Roller Skates.

FLASH! Tommy changed it into the evil Asuramon, and then to an ice sculpture.

FLASH! Koichi watched as his mom lay dying until she leapt up again, healthy as ever.

FLASH! Koji saw Koichi vanish in a stream of data only to see Lowemon standing there.

FLASH! Takuya saw Harry standing in the middle of BurningGreymon and Agunimon. The two ran at the boy who was suddenly replaced by himself, all of a sudden, all four were doing the can-can.

FLASH! Draco saw Bruce bearing down upon the class until he froze a barrier in place.

Before the next person, Neville could go up; Harry, Takuya, and Draco froze and looked up, catching something with their sensitive ears. Ron froze his eyes half glazed and he followed suit. Neville leapt forward and dismissed the Boggart. After it had vanished, Ron and Draco stood in front and behind the teacher as Harry and Takuya faced him. When they began speaking, the noise of the other students faded away and between the two "boys" another seemed to form.

Man by day, beast by night

Knowing not wrong from right

Listen to the Alpha's call

That is the pack law

Listen well as we howl,

Ye must fight till danger, gone.

As each syllable was spoken, Lupin's mind became more and more clear, a lupine consciousness bubbling up alongside his human one. As the voice fell away, Lupin knew he had to go to the grounds right outside the Entrance Hall as soon as the bell rang.

As soon as class ended, Harry and Takuya ran out the staff room and off to the Entrance Hall. Ron, being slower, was not as quick. Using his wings, Draco flew out. In two separate classrooms, Joe and Kari flew out the window, each person heading to the grounds outside the Entrance Hall.

Albus Dumbledore was heading outside after walking the grounds, before he got there; he saw a blur which separated into Harry and Takuya. He noticed three birds land by the boys, the birds actually Draco Malfoy, Hikari Kamiya, and Joe Kido. After a pause, Remus Lupin and Ronald Weasley appeared. Ron, Draco, Hikari, and Joe stood in a square around Takuya, Harry, and Lupin, each at the points of the compass. He noticed that Ron and Remus had glazed eyes and it seemed they were not in control of their actions. Harry and Takuya spoke, a third person appearing between the two with a different voice.

As the hunt begins anew,

Heed the Alpha hunting pack

Discard thou thine human flesh

'Til the hunt has ended well

With this, Remus' head came up, his whole body writhing with pain. Slowly, the man's screams became howls until in his place stood a large wolf. Ron grew a cloak of feathers, and his eyes became feral. Draco, Hikari, and Joe lost all humanity, their feather cloaks becoming wings and their bodies becoming encased with shining armor. Takuya changed the most, from a half wolf half boy to a strange mix of lion and dragon. Harry changed the least, his face becoming a mix of Harry and Takuya.

Hakuya mounted the beast, the four Valkyrie preparing to fly. With the unnoticed signal, the group set off, Albus following. When they next halted, they were face to face with Kaskana, the shadow billowing before them.

"We come as we must, to do battle for our home." Hakuya said, readying his sword.

Kaskana smiled and turned around, a careless hand turning a patch of flowers into dust. "Release me from my curse great Valkyrie."

The sword rose and fell, clashing with an edge of the other's cloak. Hawk, Raven, Raptor, and Eagle soared and dove, Lupin leaping up for the kill. Though Kaskana had asked to be killed, the shadow ducked and weaved, the combatants locked in a dance. Around them, the ground lost its green, flowers wilted, and rocks changed to sand. At last, Lupin scored a hit, a claw to the place the heart would be. However, as she lay dying, Kaskana spoke, "This wound was well scored, but it will not be enough to end me. My brothers had physical form or were bound to others. I shall do battle again, farewell." With that, the shadow vanished.

The rest of the day passed in a blur, the Valkyrie mulling over what had been said. How could they kill something unkillable? In his office, Dumbledore stroked his phoenix, Fawkes in thought. He did not know who this shadowy figure was but he was not worried about that. No, the way Remus was forced to be a wolf in the daylight, and the way he looked when he returned to human form, frail and in pain. He knew he would have to find out how to stop this before the students were placed in danger.

A.N. Normally, when I have to check an event against my own work, I would use my copies of the books. Unfortunately, my copy of Harry Potter and the Prisoner of Azkaban vanished so I had to guess. Though this chapter is a few days late, as I said before my dad was in town and I got home late each day. Yes we will see Kaskana again, and maybe she will be like Mai in tUGoD but for now, I needed to get out the Boggart scene. As always, thank you for reading and please stick around.
