Saki's POV

I was working on a song in my room, when the door suddenly flung open!

"Saki", a familiar voice yelled loudly out. Hearing it made me jump slightly as I let out a little scream.

"Onii-Chan, don't scare me like that", I scolded as I turned to look at him.

"Sorry, Saki", he apologised as he rushed up to me. "But I need your help with something very important."

"What is it", I asked.

"Ichika's birthday is coming up, and I want to get her at least five gifts", Tsukasa revealed.

"At least five gifts", I exclaimed in shock. "That's a lot, Onii-Chan! Why do you wanna get Ichi-Chan so many gifts, anyway?"

"She's been looking out for you and taking care of you for so long", Tsukasa pointed out. "It means a lot to me, so I wanna to show her my gratitude."

"Onii-Chan", I said, touched by his words. "That's so sweet!"

With this, I my mind was made up.

"Okay, Onii-Chan", I said excitedly. "I'll help you figure out what gifts to get Ichi-Chan! Let's get her as many gifts as we can!"

Ichika's POV

After spending the majority of my birthday with my friends at Phoenix Wonderland, Saki and I returned to her house.

"Onii-Chan, we're home", Saki called out as we walked through the front door.

"Saki, Ichika, welcome back", Tsukasa greeted as he came into view.

Then, he suddenly walked up to me.

"I have something to show you, Ichika! Follow me!"

After saying this, Tsukasa suddenly grabbed onto my hand and started pulling me away.

"Tsukasa-San", I started, my cheeks turning red because he was holding my hand. "Where are we going?"

Tsukasa didn't answer me, and led me into his living room.

"Behold, Ichika", he said as he gestured to the front of the couch.

I looked at it, and saw… a huge pile of Hatsune Miku merchandise?!

"What is all of this", I asked in shock.

"Ichika", Tsukasa started. "For many years, you have been there for my sister and have taken such good care of her! To show you how thankful I am, I decided to get you as many gifts as I possibly could!"

"You did", I asked in shock. "Where did you even get all of this stuff?"

"A little while ago, Onii-Chan and I spent almost a whole day going to as many stories selling Hatsune Miku merch in Shibuya as we could", Saki revealed.

"Really", I asked, touched by all of this. "You really did all of that for me?"

"Of course", Saki replied, before smiling widely at me. "Happy birthday, Ichi-Chan!"

"Happy birthday, Ichika", Tsukasa added.

"Saki, Tsukasa-San", I said.

Then, a smile came to my face.

"Thank you very much for doing this for me", I said.

"You're very welcome, Ichika", Tsukasa said. "Now then. Before you look through your gifts, Saki and I actually have another surprise for you!"

"You do? What is it?"

After I asked this, Tsukasa suddenly grabbed onto my hand again.

"Right this way", he said.

Then, him and Saki led me to their family piano.

"To celebrate your birthday, Saki and I will now perform a piano rendition of a Miku song for you", Tsukasa revealed.

"Really", I asked.

"Yep", Saki replied. "Onii-Chan and I spent a lot of time learning to play this song, so we hope you enjoy it!"

While Saki was saying this, Tsukasa pulled out a seat at put it down near the piano.

"Now, without further ado", he started. "Ichika, please sit down and enjoy this special piano duet by the Tenma siblings!"

After hearing this, I did as told and sat down on the seat Tsukasa brought out for me.

Him and Saki then sat down by the piano, and looked at each other.

"Saki, are you ready", Tsukasa asked.

"I'm ready, Onii-Chan", Saki replied, before looking at me. "We hope that you enjoy this performance, Ichi-Chan!"

"Now", Tsukasa started. "Let us begin!"

With this, Tsukasa and Saki began their performance. As I listened to them, another smile came to my face.

Saki, Tsukasa, thank you both very much for doing all of this for me. I am very happy to have met you two.
