Olympia Soiree Catharsis Review: Back to Tenguu Island

Play time: 60+ hours

Common route: 2 chapters (equivalent to around 5-6 hours of gameplay)

Gets re-introduced to Tenguu island and how much things have changed last 2.5 years
New character sprites for same characters who grew up like Hairi or Asuha, for LIs Tokisada & Himuka get new outfits and sprites
To keep everyone on the same page in the common route, they made sure all the main plot points from OG game are relayed to the LIs that missed out in their routes (i.e. Himuka's identity, etc.)
Introduced new characters and more worldbuilding, but there's one new side character I really dislike
After common route, there's a selection screen. Just like in OG game, we can play: Yosuga, Tokisada, Riku and Kuroba (in any order)
Then Himuka will be unlocked. After Himuka, then Akaza unlocked
There's no secret LI route or anything. Just 6 routes.

LI ROUTES (May have minor spoilers like thoughts/moments so skip if you don't wanna know)

Riku

Plot gets quite predictable after Ch 4
Felt it gets dragged on for no reason and the climax was tame/vanilla
Some cute moments here and there, Riku is more deredere than tsun now
Cute bro moments with Akaza
Wedding scene is soooo beautiful, I love how detailed it is. not just yay married but they show us the customs and process of a wedding ceremony in Tenguu and Tennyo from morning till night.
THE MAN HAS SUCH SELF RESTRAINT such a gentleman haha, wish he can be thirstier
CGs are ok, a lot came later in the route. I think the ones in the first game were visually prettier LOL
Cero D lines but not as Cero D CGs 😂
Plot: kinda boring and vanilla, 6/10
Romance: kinda cute but not enough steam, 7/10

Yosuga

HOLYYY DLSKFNSLDNF i feel like im playing another game! Cero F hahaha
Ahhh i love him so much! Such a possessive man!!
There is more world building in his route than Riku's but man, I wish to see more relationship development as well
I love all their cute scenes!! Even the scenes with the other LIs are funny bc they know that angry Yosuga is scariest LMAO
Romance is steamy and cute, and seeing them care for each other is beautiful and it feels they love each other a lot
But I wanted more, like relationship development cuz the route focuses more on the systematic issues that exist in Tenguu plus a bit of Yosuga character development
I still enjoy it and the wedding is so touching i cried 🤧 🤧
Plot: 7/10, a bit more interesting
Romance: 8/10, they are too cute!

Tokisada

My my, this man got a glow up!! Look at those SHOULDERS
Such character development! He has matured so much now that he's chief of Green (shown in trailers)!
The voice got DEEPER and calmer! I can't!!
Low key missed him calling MC "Onee-san" but oh well
He's sooo cute when he blushes bc he's usually calm now! THE GAP!!
The plot had similar themes on discrimination due to color system like Yosuga's and Riku's but it was refreshing exploring from his perspective as an Outsider
Their relationship dynamic is honestly so beautiful, he's so gentle and kind to MC!!
I cried so much at their wedding scene 😭😭😭
Low key looks like Tengoku Struggle Goemon now which makes me fall harder for him AHHH 💖
Plot: 7/10, predictable but still good
Romance: 9/10, I can't believe how much I love their chemistry! He was not even my oshi in the first game

Kuroba

Route is quite interesting and doesn't overlap as much, more focused on Haku and its progress medically
Nagusa is still the most annoying side character
A lot of cute bromance scenes with Akaza and Yosuga
I don't super like their dynamic and the way he treats her is kinda turn off sometimes.. he was my least favourite in the first game and he continues to be in this game I guess
CGs are the most explicit so far, too bad I'm not enjoying their romance
The best part about this route is Doma
Plot: 7.5/10, least repetitive in terms of the focus but also still have the same theme on discrimination
Romance: 5/10, I just don't see it

Himuka

Plot has a bit repetition from Tokisada and Riku plot but overall it's new and interesting
A lot more development on the main plot from the common route but it is still not completely addressed by the end of the route
I like Himuka's character development here, from someone juggling his identity between human and god, forgiving himself and reaching self-acceptance
Interesting to see everyone so involved in the plot and played a huge part
He and MC have quite a good relationship dynamic
If you like Virche Evermore's Mathis, you will like him for sure
Daifuku MVP
Himuka is visually not my style but he's really sweet to MC
His route seems to be a prelude to Akaza's which makes me excited
Plot: 7.5/10, quite interesting but some repetition and not a lot of memorable scenes for me
Romance: 7/10, cute but he's not my cup of tea

Akaza

Honestly, from the start, u can see how biased the writers are for him (which i dont mind at all haha)
THIS IS A LONGGGG ROUTE like it's longer than everyone else's
It is not just HIS route but it felt like the GAME'S route because the main plot is finally addressed and resolved here
He's soooo sweet, gentle and husband material I CANTTTT T^T Every line is an iconic line, the VA is not paid enough!
The man is training his self discipline... BUT WHAT ABOUT MY SELF DISCIPLINEEE???
I LOVE when we learn about childhood stories of Riku and Akaza or when Yosuga first met Akaza! SOOO CUTEEE
Some moments of the route feels like MC is third wheeling Akaza and Riku because their bromance is sooo cute here (it's very friendship-themed) I LOVE THAT THE VAs of Akaza and Riku are also BFFs IRL
OMGGGG THE ANIMATIONS, movie level animations only in this route? Wow the bias but I'm loving it like they even animated the water so realistic! WOWOW
THE CGSSSSS are on another level like this route gets a lot of "OTHER" CGs too so it feels like so many CGs in this route
EMOTIONAL ROLLER COASTER! This route has everything: action, emotion, story, friendship, love, pain AHHHHH EVERYTHING
The wedding is soooo pretty like how is everything so beautiful? Why is this man so beautiful??
Plot: 100000/10, he's my S tier husbando so I may be biased but it's literally the completed end of the main plot
Romance: 1000/10, THE VOICE ACTING, THE VISUALS, THE LINES!! He's a perfectly thirsty man!

LI Ranking: Akaza >>>>>>>>> Yosuga > Riku= Tokisada > Himuka> Kuroba

Route Ranking: Akaza >>>>>>>> Himuka = Yosuga > Tokisada > Riku > Kuroba

Overall thoughts and wrap up

Stepping back after finishing all six routes, Olympia Soirée Catharsis feels like a very indulgent, fanservice heavy sequel done with a lot of care. Visually, it is stunning. The art is consistently beautiful, from the refreshed character sprites to the CG composition, lighting, and details. The weddings especially stand out. They are not just “end scene celebrations” but fully realized cultural rituals, and that attention to worldbuilding makes Tenguu feel alive in a way few otome games manage. Akaza’s route in particular feels almost "unfair" in how much budget and polish it gets, but honestly, it works because it delivers the emotional payoff the entire series has been building toward.

The voice acting is another huge highlight. You can really feel how much the cast understands their characters after the first game. Subtle changes in tone, maturity, and emotional restraint make the time skip believable, especially for characters like Tokisada and Himuka. There were many moments where a single voiced line carried more emotional weight than an entire scene of dialogue, and that is something this game does extremely well.

Structurally, Catharsis is not perfect. There is noticeable thematic repetition across routes, especially around the color system and discrimination (a lot of misogyny that raises my BP too). Some routes feel stretched, others feel like buildup for Akaza's route to tie up the loose ends rather than fully standing on their own. A few routes may feel predictable or a little safe/vanilla. But if you are here for character moments, emotional payoff, and seeing these relationships breathe after the chaos of the first game, Catharsis delivers.

What I appreciated most is that this sequel does not feel shallow. It is clearly written for players who cared about the original story and characters. It respects your time investment, deepens existing bonds, and gives closure where it matters. All the routes add texture to the world and show how much everyone has grown.

In the end, Olympia Soirée Catharsis feels exactly like what its name promises. It is an emotional release, an indulgent. Tho sometimes biased, sometimes messy, but very sincere in its love for its characters. If you loved the original game, this is not optional content, a must play!
