In my country(Korea), today is September 9.
And in the morn, when I opened the melty blood, I see a surprising screen!
Len and White len was eating a cake larger than their size.
It was an amazing sight, and I saw a little text, "HAPPY BIRTH DAY, LEN!"
I today realize that it was Len's birthday.
Me wonder other characters have an easter egg like this.
I've heard that in Christmas, there's a similar hidden title screen like this.
Anyway, Happy birthday to little cat and the tsundere, and any other peoples that September 9 is birthday!
