Shingen received news that one of his concubines gave birth to twins, one boy and one girl. This was quite surprising because this was the first time this had happened in the Yamazaki clan, the boy's name is Park Gun and the girl's name is Guest. Gun was born five seconds first before her born, they were both born with the same eyes as Shingen, black eyes with small, round white pupils. Even though they are twins, they have different personalities, Gun has a rough and blunt personality while user has a much softer and more innocent personality, they are only five years old now.

One afternoon, Shingen was in the castle hallway and looked out of the window, then he felt the edge of his kimono being pulled a little, then when he glanced, it turned out to be his daughter who was holding a teddy bear and look at him with big eyes, innocent gaze. Then he saw one of the maids pick her up while bowing in front of Shingen.

The maid spoke in a slightly trembling and nervous voice when she felt the sharp and cold gaze from head of the Yamazaki Clan, while Guest just kept holding her teddy bear and looked confused.
