The two dates took place in various places in Yokohama.

Spotify is in the OP all along. ('協力' means 'co-operation')

The VA credits during the ED are now showing the full names of Suzuki and Tani, as opposed to only their surnames shown in previous episodes.

So far, Rihito is the only other character with their full name shown during the credits, since both parts of his name were mentioned in this episode.

Just like the other Meikoh Wind competitors, the goats in the bouquet corresponds to the surname of Yuna Yagi. Although this time there is no corresponding Kanji in her surname to the animal, the reading of her surname shares the same phonetical reading as 'goat' (yagi), despite the literal characters being 'eight tree'.

Minor detail regarding the bouquets for the two Meikoh Wind competitors:

• Rinna Sarukawa (申川 りんな) got a bouquet with a monkey couple, because the 'saru' (申) Kanji in her family name is 'monkey' in Japanese. (This Kanji variant is commonly used in the context of the 12 animal zodiac, rather than the actual animal itself)
• Yotsuha Ushikawa (牛川 四葉) got a bouquet with a cow couple, because the 'ushi (牛) Kanji in her family name is 'cow' in Japanese.

Fidgeting Anya (Loop):

This shot reminds me of the first opening of The Apothecary Diaries, "Hana ni Natte" (Be a Flower):

My attempt as translating Bachel's contract with the Night Mist Troop:

-CONTRACT-
Bachel is employed to the Night Mist Troop under the following conditions:

• The lives of our members are our top priority, and orders must be followed at all times
• The contract period is indefinite until the contract is terminated

Spring
Bachel

The alphabet used in this series so far mostly transliterates into English, but I noticed that this contract was transliteration into Japanese (romaji) instead.

In case anyone missed the detail in the post-credit scene:
The door plate numbers correspond to a part of their names in a wordplay fashion:

MORI HITO (1)
NI CO (2)
MI HARU (3)
KAN SHI (4)
KEI GO (5)

We almost had an entire episode where we didn't get to hear Maomao's voice, which also almost happened back in Episode 42 (Season 2 Episode 18).

All three titles share the same manga publisher, Shueisha.

It's always interesting to hear a VA's range by voicing both parent/child roles in the same series.
Other series that do this that I can think of include Welcome to Demon School! Iruma-kun, and The Apothecary Diaries.

If anyone noticed, some of the ending sequence visuals are (camera-)focused on Carmilla.
For previous episodes, it was Lily for Episode 2, and Loewe for Episode 3.

Usually when a character reads a manga in a manga or anime, I check to see if it's a parody or something.

The manga that Raido's younger sister was reading is an actual manga series, Denki-Gai no Honya-san, by the same author as Aharen:

I noticed that the Kaykay Sisters' hairstyles closely resemble the hairstyles of the members of the J-Pop group Perfume (Nocchi, Kashiyuka, and A-chan, respectively).

In case anyone missed it: The ED for Episode 3 is a solo vocal version sung by Akane's VA

The ED is a cover of Ken Matsudaira's hit song "Matsuken Samba II":
