Of all the years Kai knew Aichi, watching him…. studying him…

From the day they met as young children, Aichi was meek… Kai had given him hope to become brave and strong like Blaster Blade.

Since the day of their first Vanguard fight against each other and days after, Aichi was innocent, a bit shy… and had grown confident. Kai had not admit of anything to Aichi if he was strong or not.

Guilt overcame his heart as he told his last words to Aichi, of him being "weak", before leaving Team Q4. He had made the same mistake as before with Ren. His guilt was not doing anything… only observing from a distance. His guilt in not telling Aichi the truth.

Kai knew how much Aichi meant to him and one day…

He would show and say it.
