Showa: "It's gotta be me." Heisei: "Look, a beetle!" Reiwa: "Obviously me."
About
You might think "the old days were better," "I want to go back to Heisei," or "it's hard to live in this day and age." Who knows?
So, I've personified the [Showa], [Heisei], and [Reiwa] eras.
*This is based on my heavy personal bias, so don't get mad.
Characters
Appearance: Male. Black hair slicked back. Red eyes with dark circles and a goatee—a corporate slave look. Scars all over his body. A very "men are men, women are women" aesthetic.

Not a 0 or 100 thinker. Maybe fits the 50/50 Japanese mindset best. Recommended for those seeking stability. Also has a cute image.

"Aren't both of them lovely? I don't really know though~"

"Discrimination is so over, lol. Equality for all ages and genders, right?"
Loves Guest. But never says it. Even if he did, he'd chicken out and confess over LINE.
