Tapu Koko in Kanto!

It was a normal day in the Alola region. Tapu Koko was resting in his shrine. Until a wormhole opens up over the islands. People panicked and hid in their homes. The Pokemon hid in caves or burrows. Tapu Koko went to investigate. But when he did, he got sucked into the wormhole.

The Alolan champion had returned to Kanto for the summer. She decided to take a walk in the forest, before hearing the all too familiar cry.

"KOKO!"

She was startled by the sound, and very confused. She ran to the source of the noise. What she found, however, was Tapu Koko in his human form. (yes he has a human form in this)

"T-Tapu Koko...?"

The champion said in shock. Tapu Koko looked up, seeing the young girl. He felt a little relief and spoke.

"Champion Selene...what are you doing here? Did the wormhole get you, too?" Selene looked confused before responding.

"What wormhole?" Tapu Koko furrowed his brows. "Child. With all the adventuring you do, surely you saw the wormhole over Melemele."

"But Tapu Koko, we're not on Melemele..." Selene said with a nervous and worried tone.

"What on earth do you mean?" The island guardian said in a rather frustrated tone. "Tapu Koko, we're in the Kanto region.

"WHAT!?" He exclaimed. "The Kanto region!?" Selene grew afraid.

"Yes!..." Tapu Koko collected his thoughts for a moment. Then he asked, "Why are you here?" Selene sighed, "I'm from the nearby town. I'm staying with my dad for the summer."

"I see. If you don't mind. Might I stay with you for a short while? I don't know how I shall return to Melemele. However, I do believe I need your help to do so." Selene smiled and grabbed his hand. "No problem! Follow me!"

Selene led him to her father's home. She sat him down on the couch. Tapu Koko looked at some of the old photos of Selene on the wall. "You have a lovely home."

"Well thank you! But it's my father's." Selene said with a small smile.

"You look so adorable with the cake on your face." He said, chuckling.

"What?" Selene was confused. Then she realized he saw the pictures. "NO! Don't look at those! They're embarrassing!"

"Oh come on. Look at that cute little face! I could just pinch those little cheeks!"

"I don't have a cute little face..."

"Yes, you do!" He cooed and pinched her cheek.

Tapu Koko continued to coo over her and pinch her cheeks. Eventually, her father came home. After a quick explanation, her father agreed to let Tapu Koko stay until he could get in touch with Professor Oak for help.

"Child, you are Alola's champion. I am obliged to guard you."

"That's fine, but can you get out of my room?" Selene wasn't a fan of Tapu Koko watching her sleep.

"Very well. Sleep tight." He left the room.

Early in the morning when Selene's father was getting ready for work, he found Tapu Koko asleep by Selene's bedroom door. Showing he had been true to his word to guard her. While he slept, Selene's dad made a phone call to somebody. But who?
