这张贺图其实有一些彩蛋(?
1.红色的彩带连接着芽衣跟琪亚娜，代表两个人的羁绊。
2.蛋糕一般都是砸在寿星身上，但琪亚娜帮芽衣挡住了。
3.地板的黑白方格设计是来自漫画版，姬子家地板。芽衣、琪亚娜、布洛妮娅是一起住在姬子家。
4.右上角压住布洛妮娅的鞋子是姬子血色玫瑰的设计。
5.上面的爆衣是血色玫瑰胸部的地方，姬子上半身是裸的。
6.琪亚娜的鼻子是外露可以呼吸的XD

This image actually has some eastereggs:
1. The red ribbon connects Mei and Kiana, representing the bond between the two.
2. The cake usually hits the birthday person but Kiana helps Mei to block it.
3. The black and white checkered design of the floor comes from the comic version, Himeko's floor. Mei, Kiana, and Bronya live together at Himeko's house.
4. The shoe on Bronya in the upper right corner is the design of Himeko's Bloody Rose.
5. The black shirt belongs to Bloody Rose, so Himeko's upper body is naked.
6. Kiana's nose is exposed and can breath. XD
