3rd place: Isekai Reincarnated Dungeon Master: Reincarnated, I'll Make the Hot Spring Dungeon

Isekai Reincarnated Dungeon Master: Reincarnated, I'll Make the Hot Spring Dungeon
From Amahara, creator of Interspecies Reviewers, comes a rule-breaking dungeon management fantasy powered by modern Japanese hot spring knowledge!
“You’ve been reincarnated as our dungeon master.”
Reborn into a fantasy world and put in charge of managing a dungeon, I quickly realized the usual strategies—hoarding rare treasures or unleashing powerful monsters—weren’t going to cut it.
What’s really needed is simple: get as many visitors as possible.
“Alright... I’m building a hot spring dungeon!”
With rejuvenating baths and beauty-enhancing waters, infused with the spirit of Japanese onsen culture, the hospitality is top-tier.
Word spreads fast. Soon, beauty-obsessed female knights and noble ladies are flocking in droves. Even queens are diving in with sparkling eyes.
Before long, this hot spring dungeon begins to cause ripple effects on a national scale—reshaping the economy, diplomacy, and society of the fantasy world in unexpected ways...!?
This novel edition also includes a brand-new original story featuring Lady Auf as she challenges the dungeon for the very first time!
2nd place: Confession Rehearsal: Tokyo Spring Session

Confession Rehearsal: Tokyo Spring Session
A new chapter in the HoneyWorks "Confession" series—now following them as working adults!
Since graduating from Sakuragaoka High School, Natsuki and the others have been chasing the dreams they once envisioned.
Souta and Akari prepare for their wedding,
Yuu and Natsuki welcome a new addition to their family,
and Haruki and Mio work to close the emotional distance that’s grown between them.
A new “spring” of reconnection and renewal begins to bloom once again—tied by fate and time.
1st place: King's Proposal Vol.8

King's Proposal Vol.8
On the school trip, produce a date between the First Generation “Knights” and Ayaka!
Since the school festival, Kokui has been avoiding Mushoku.
Though Ruri realizes it’s just Kokui’s “shy when in love” mode, she has mixed feelings and doesn’t want Mushoku to understand that.
Amid this tension, the students head to Hokkaido on a school trip to the Garden of the Void.
There, Mushoku finally reunites with Kokui—but…
“Making me wait? You rogue.”
“I’m afraid of heights…”
Something about her is way off! Is she glitching again!?
Even in Ayaka’s form, Mushoku and Kokui can’t seem to get back their usual rhythm—
when suddenly, the supposedly dead First Generation of the Knights appears before them!
“We've long awaited this day. I’m truly overwhelmed!”
And now, they ask Mushoku for help planning a date with Ayaka!?
