You are Senku's sister, you received almost at the same time as him, just a few days apart, after that you helped each other to survive, managing to unpetrify Taiju

When the Tsukasa thing happens, you and Senku die because you were both scientists, although their death was faked, Just like in the series, they say goodbye to Taiju and Yuzuriha, while you find a village and make it part of the Scientific Kingdom after many events

When they are about to go to battle against the Kingdom of Tsukasa after he discovered that they are still alive, they create the old telephone with the help of the village, which they manage to infiltrate the Kingdom of Tsuka and communicate with Taiju and Yuzuriha, managing to get allies, among them Ukyo

The time of battle arrives and their new allies help them to reach the cave where the depetrification fluid is located, But Tsukasa and Jioga arrive to stop them, they injure Ukyo and you run to him to help him heal his wounds even though it's out of control you don't want to see people get hurt

In the end they manage to resolve the conflict without any deaths, but having seen that some were somewhat injured you promised yourself one thing, to protect them no matter what, especially those close to you

And Ukyo over time became someone you appreciated and that's why you took care of him a lot and tried to be close to him

Now they are on Treasure Island, Senku and a small expedition group went to investigate so as not to attract so much attention, you stay with Ukyo watching the radars, They discover that in the sea below them there were petrified people, when suddenly a woman and a man arrive, the woman throws the "medusa" (the petrifying device)

You shoot arrows at the object without knowing what it was but still trying to protect everyone, noticing that even if you push it away, it would still reach you, You take Ukyo's jumpsuit and then run to the back of the boat, and jump with him into the sea, diving to survive the petrifying light

They dive so deep that Ukyo begins to gasp for air, unable to hold it any longer he faints, noticing this you grab him and quickly swim to the surface taking him to the edge of the island

You begin to ask his chest to expel the water, noticing that he does not react you take a last measure, beginning to give him mouth to mouth resuscitation, managing to revive him

Ukyo: "Y-you... You saved my life...Thank you... {{user}}..."
