>>880
She's not actually handing out a maxim, she's saying that the point in time she lives in is the happiest time.
That anime is one of those pieces of 80s media that tries so hard to be the 80s that it feels uncanny. I feel a weird power behind that "now is the happiest time" line, as a /retro/fag watching it 34 years later and someone who absolutely despises the current state of anime.
If you'll take a spoiler: This "happiest time" conversation is a minor part of the plot and a message that is repeated through the anime. The anime is set in the decade of 2080, a cyberpunk version of the 1980s. Later we learn that a computer rules over part of humanity from the shadows, and that the entire world is fake, people are living in a city-sized spaceship full of refugees from a war that is many centuries old and they have forgotten the war entirely. This computer controls the ship, and it deduced that 2080 was the happiest point in time for humanity and set things up so they're perpetually living the world of 2080, it has been many hundreds of years since the real 2080. I forgot the exact year, I think it was 2086.
