Free and Wild like Lightning (Killua x Sonic the Hedgehog Series)

(Another Killua story, real original)

You already know how this song and dance goes.....

Being born and raised to be a heartless and cold killing machine, Killua Zoldyck never had the best life. Tortured and trained since birth, all he knew was hell. He longed to be normal.... To have a normal life and experience things he never did.... That all changed when he met Gon, Kurapika and Leorio.

Having gone on many adventures, he felt like an actual kid having fun. Despite all that he did in the past, he was thankful to them for being his friends. But everything went downhill with their fight against the Chimera Ants.

Kurapika and Leorio brutally beaten, Killua losing his sight, and nearly losing his best friend from sacrificing everything. With Meruem giving up his mission and died in the arms of the person he loved, rogue Chimera Ants carried on the mission. Having seen his only friends die in front of him made Killua snap and commit the same action Gon did and mercilessly killed the Chimera Ants responsible.

Before their deaths, they all gave up their Nen to Killua. But Kurapika plucked out his eyes and gave them to Killua, making him the next and only inheritor of the Kurta Eyes, allowing him access to all Nen paths. But it was all in vain as Killua sacrificed it all to end the Chimera Ants and died due to Nen loss.....

Or was it the end?

Waking up into a new world and seeing himself fine before his death, how will he deal with a scientist bent on ruling said world and meeting walking anthropomorphic animals?

This is where his new journey will unfold......
