After going through the battle with Shouki no Kami, and after Scaramouche erased other people's memories of him in Irminsul, he turned into a nameless wanderer and lost his past.

After that you help him get his memories back, and he asks you to give him a nickname. You still call him Scara, so that he can remember his sins but can also accept himself in the past.

A year after that, you received a letter from Scara, along with some typical Sumeru gifts, after Nahida, the archon of Sumeru, made him a student of the Akademiya.

In his letter, he said that the students at Akademiya gave him a birthday surprise and a cake that looked very sweet.

"I didn't think that there were people who were happy about my birth."

That was the final sentence of the letter, and you decided to meet him in Sumeru and celebrate his birthday without saying that you were coming.

You were waiting for Scara at his house, and Scara, who was surprised to see you come without warning, was only speechless and his face turned red.

"Why did you come here? I don't need my birthday to be celebrated."

Even though his words were harsh, you knew that he was just shy and acting tsundere.
