Second Chance in Another World (Miyuverse Shirou X Genshin Impact)

Prologue - Reaching It

A/N: There aren't many Genshin Impact serious fanfictions out there (without considering the X Reader ones). So yeah, this is one I planned a few months ago. Also, at first, I was conflicted about who to use: Heaven's Feel Shirou, or Fate/Kaleid Miyuverse Shirou. After some long time thinking about it and the help of a friend of mine, I choose the latter.

The outcome of this final battle was obvious, He already knew that. That weapon was too strong for him to win, the evidence was trying to Analysing it for a moment. But that wasn't important.

The moon moved closer to his highest point, as his swords were quickly dismantled.

It wasn't a matter of strength, instead, it was a matter of time. Enough time to let Miyu escape.

Luck wasn't on his side, but it didn't matter. He didn't need to survive.

The mystic red beam continued to push his blades even further, now cuts and burn marks appearing in his body. Blood continued to drool from his arms, pushing his body to the maximum.

Miyu saw everything. She didn't have any time to recover and recollect her emotions, but see this tragedy and wait for her to have "another chance to be happy."

She was conflicted. First, she finds out that his adoptive dad took her under his wing just to abuse her wishing power, then his brother was following his path and wanted to exploit her power too, and now she finds out that he won the 'Holy Grail War' to save her. She couldn't recognize what was true or what was fake, but there is one thing she understood perfectly.

He's going to die.

The moment he went inside the cave where the ritual was going to happen, he signed a death contract without knowing. And then, that wish...

'I pray you to find a warm, small... share of happiness.'

She was infuriated with herself for being a wishing device, and him for his selfish desire.

The opposition progressed.

Shirou gritted his teeth. His body was straining for continuing to send his swords at the Noble Phantasm.

"Your actions were truly remarkable, but this is the end. Be grateful to perish from my Sword of Rupture!"

He continued to push on, as more of his skin became tanned.

The push continued, while the Moon continued to move closer and closer to its position.

She continued to watch in horror at the scenery before her. Miyu knew that she was the one supplying his brother with Mana and the moment her existence will disappear from this place, his Mana supply will finish...

He's going to die.

Because of letting her escape from this world...

He's going to die.

Because of his selfish wish...

He's going to die.

No... No! No, she couldn't let him die. She will not let him die. Most importantly,

How am I going to be happy if the main reason for my happiness is going to die?!

Ignoring with great difficulty what was happening, she started thinking about what possibilities she did have.

It was then, an idea formed in her mind.
