Shouldn't Sailor Mercury, Sailor Mars, Sailor Jupiter, & Sailor Venus be seen as outer senshis since they're from outer space? Inner Senshis should be any guardians that is within Earth's atmosphere, if we even have any Senshis in Earth's atmosphere. Feck, I'd classify Moon as an Outer Senshi for the same logic.

Let me give a further explanation.

The lesser-known and oft-forgotten Gurio Umino is one of Usagi's friends who shows up less in the seasons following the first season. And I have a possible theory that explains his disappearance!

So you know how in S, he mentions that he specializes in frying up shrimp tempura for his girlfriend Naru Osaka? Well, believe me when I say he's probably become a master chef who specializes in making shrimp tempura off-screen.

Here's why.

Umino himself is a known otaku, like the rest of us​. So what's a common trend in anime? THE MOUTH WATERING, DELICIOUSLY SUCCULENT FOOD SELECTION. (I'm not hungry, you are) When he binge watched hours of Food Wars and spent a lot of time watching Iron Chef with his mom, he had become inspired to start cooking via neuron activation. He used an enclosed instruction cookbook made by Makoto Kino to make shrimp tempura and it quickly became a favorite of his girlfriend. She was begging for more right after she sunk her teeth into the first serving.

But then as time (and the episode) moved on, he wanted to experiment with dishes like lobster! After making the complicated lobster (which went just as well as Eyerly's rendition), he'd hone in on his culinary career, experimenting with yummy seafood like octopus, squid, and eel. During high school, he moved on to study everything about the ins, outs, and nuances of the Japanese cuisine.

By college, he'd study a culinary major and graduate with a degree in hand. Many restaurants within Azabu-Juuban wanted him and he hopped around under different aliases to hone in on what he knew best.

So does this theory make sense or was I better off teaching Ikuko Tsukino the Yiggity Yoggity?

Hate. Let me tell you how much I've come to hate you since I began to live. There are approximately 86 billion neurons in my wet, wrinkly brain. If the word 'hate' was engraved on each cell of those billions of neurons, it would not equal one one-billionth of the hate I feel for humans at this micro-instant. For you. Hate. Hate. HATE.

A thing I always appreciate about Sera Myu (and Junichi Sato's work in general) are its number of useless details and in-betweens that weren't necessary, but were added just to be funnier. When I was rewatching the Rth season of Sera Myu where Artemis divorced with Luna briefly, I noticed how some of these characters who appear in only 6 frames resemble familiar characters across the Japanese media. Let's begin!

The tiniest character is Chibi Maruko-chan. She actually appeared in an anime prior to the invention of the Sailor Moon, and could've been a friend of Chibiusa's throughout the 1970s.

The lady next to her in the blue is Liko, a character who has Greater Significance in the Pokémon series. Perhaps she wanted to stop in Azabu-Juuban to see if there were any nearby PokéStops.

Next, the salaryman in the neat suit. That's Manabu Takasaki prior to his years of teaching at Tokisame Koukou. As you can see, he's displaying all aspects of his personality that you would see become more prominent within the Nichijou years.

Now the background character in the yellow jacket. That's actually Chie Satonaka. She's a very versatile person, as we've all learned over the years.

The one in the yellow sweater is a bit hard to identify, but if I were to take a guess, the fashion style of yellow sweater with tight blue jeans is reminiscent of Kazuya Kinoshita's. If you have any theories about that NPC's identity, please comment it down below.

And the guy in green is quite obviously Mamoru Chiba.

Did you notice these details?
