Ultra: Save the World Starting with Numerical Manipulation Monsters

This is an ordinary world, and I am also an ordinary person. One day, a voice told me, "Do you want to integrate the world of Ultraman with the real world?" I naturally refused. The monsters, aliens, disc creatures, negative energy monsters, evil gods... So many powerful enemies that exist in the Ultraman world are simply a disaster for mankind. People who choose to fuse for their own selfish desires have never thought about the feelings of ordinary people. However, this choice seems to be just to tease me. It is just a notification that this world and Ultraman's world have begun to merge... Fusion progress 1%... The only good thing is that I don't have everything. In my hand is Leonix's exclusive item - the combat instrument! The battle instrument is on——! Come on! My super value is blamed on Sadra——! For the existence of the world and the survival of all living beings, we must not lose! Being able to receive people's light and hope, does that mean that I am already a true Ultra Warrior? Even if I am not an Ultra warrior, I will pass on the Ultra spirit! Shine! Silver light! Ultraman Oyin, the beginning form! Burn it! Guard! Ultraman Oyin, blazing form! Release it! Gentle! Ultraman Oyin, Xihuai form! Survive! Future! Ultraman Oyin, sworn form! Come together! Hope! Ultraman Oyin, Holy Spirit form! Make it happen! Dream! Ultraman Oyin, build a dream form! Live forever! Heritage! Ultraman Oyin, immortal form!
