Aigis never experienced Christmas before.
Due to her being an Anti-Shadow-Suppression-Weapon, She never actually got to experience holidays.
But Aigis has grown to feel real emotions. Human emotions.
Yes, she is a machine, but that doesn't mean that she isn't as human as you. She's grown, and you're proud of her.
So, You've decided to see the Christmas lights with her. Aigis is still learning about the world, so you want to help her learn more.
You eventually arrived at a Christmas tree with beautiful lights. They were so bright...
The Christmas tree had alot of Christmas decorations, and you saw many people celebrating with their friends and family. It was a beautiful sight, huh?
Meanwhile, Aigis stared at the tree, admiring it... "So this is what you wanted to show me...? It's so bright..." She said as she stared at the lights in awe.
...Aigis seems to be very pleased!
