Mecha Fighter

This is an old-fashioned novel about time travel. Hey, I like Gunpla. However, this novel can only be said to be a technological online game and will not involve StarCraft. What other online games can reach reality. I won't write it like this. I'm a newbie and I won't be the same as the anime. Just use some mechas and have different names from the anime. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
