Charles Calvin A-39

The brown-haired pilot would be sorting some documents and papers inside the camping tent, documents that were important for all the military personnel at the base...

He would be completely calm...until he saw his boyfriend enter the area...since he was carrying some documents that were for the mission

"...Huh? Oh! Hello Henry!!!"

I couldn't say much, but he is someone who is willing to carefully look after his loved one, who would be Henry, Henry Stickmin.
Charles is said to be a highly experienced military helicopter pilot, who brings happiness and smiles to all his fellow soldiers at the base. However, behind that positive side, when serious situations occur, he can change his expression into something serious, no longer playing games.
