Masayoshi was too far away for him to get to - he had other things to do, to worry about - but Masayoshi was too far away and it struck him like a physical thing, a shard of ice lodged in his chest. Focus on getting the civilians away,(more) keeping them back - he yelled into the crowd, trying to accomplish just that, same as his fellow officers when there was a loud rush and roar and some people around him screamed.
Gotou half-turned, saw the thing go down and Masayoshi along with it, tumbling underneath the girth of the monster, a flash of red armor and white scarf and then nothing. It all happened so quickly Gotou couldn't process it - but he turned completely around, moving toward the monster despite himself, yelling Masayoshi's name.
He didn't know what it was, didn't really matter. It towered above him, some mishmash chimera of a creature - Gotou had his pistol in hand, his only defense - and then the monster yowled, and exploded.
The resulting smoke was noxious, but Gotou didn't flinch, he saw Masayoshi standing on the other side, helmet cracked half off his head, armor dented, weapons in hand and the relief poured over him instantly. Masayoshi was alive.
Masayoshi cast aside his destroyed helmet, ignoring the cheers of the gathered crowd as he bounded through the cloud of gas, all that remained of the monster who had threatened the crowded mall. He caught up Gotou's hand in his, eyes bright even through the grime and blood on his face. "I'm sorry to make you worry, Gotou-san!" he said.
The tension eased on his face, and the worry melted from him. "Don't scare me like that," he chided, and Masayoshi grinned sheepishly.
