Hey Absolute Students,

I hope your August went well. The team has been hard at work on Episode 2 and can’t wait to share some more new things with you! There’s lots to get into today, so let’s get started!

Akupara Direct and Livestream!

First off, we are celebrating the Akupara Games 10 year anniversary by joining the Akupara Direct and Livestream on September 6th!

In the Akupara Direct, we will showcase multiple games from our library with a special new reveal for Kumitantei! That’s all we can say for now, so be sure to tune in! You won’t wanna miss this!

The Akupara Direct and livestream will be on the Akupara Twitch channel starting September 6th at 12PM PST / 3PM EST.

Summer Fan Art Contest 2026 Winners!

Thank you to everyone who participated in the Summer Fan Art Contest! Every piece made our eyes sparkle and filled our hearts with joy! If you would like to see more art from the contest, then join the Kumitantei Discord!

The Grand Prize Winner is @that_awkward_redhead with her gorgeous art of the cast enjoying a summer sunset!

The five Runner-Ups are @starrynorijima, @prettyrhythm, @anodddutchintrovert, @devillierss1, and @guardianrosaria! 

Sakuya and Tamotsu Skill Card Animations

We have two more Skill Card animations ready for you to view! This time they’re for Sakuya and Tamotsu!

New Character Sprites for Nyanus, Kaguya, and Tamotsu

Alongside the new Skill Card animations, we have some new character sprites for Nyanus, Kaguya, and Tamotsu to show off!

New-and-improved Cosmidors

One more thing, we’re excited to share that we’ve completely overhauled the Cosmidors minigame leading into Episode 2! It’s now a lot more quick paced and dynamic, and features a bunch of new enemy types. We like to call it Cosmidors DE!

Long time fans may recognise this as very similar to a minigame in a fangame some of our staff previously worked on, but we can assure you Kumitantei will not be hitting a Dead End any time soon. We will share more details on the revamp a bit later!

Kumitantei x Montabi: Akupara Deckbuilding Cat Duo

Earlier this month, our friends, Mankibo, released their deckbuilding creature-collector Montabi! 

Play one of three playable trainers each with their own abilities and charms for you to use to turn the tide of the fight! Every Montabi has their own deck and strategies for you to play with and take advantage of the enemy’s weakness! Navigate the 3x3 grid to dodge the enemy attacks and damage the enemy.

We have a new bundle with them that you may check out where you can get 10% off when you bundle!

September Character Birthdays

September 23rd: Shigure Ogasawara

Kumitantei Character Tier List 

Did you know that there is a Kumitantei Character Tier List Maker? How would you rank all the characters in Kumitantei? 

Come join the Kumitantei Discord to see how your rating stacks up with others!
