I tag "dragon" for Veldora, though he barely appears and is in his human form, but it feels dishonest NOT to tag him. Then again, I follow a web comic where the author tags characters whose elbow is slightly visible in one panel.

This is (to me) the highlight of the Founder's Day Festival that's already aired in the anime that I hadn't read prior to viewing,* but... honestly, the anime is better—and not just because the fight scenes and so on, but also for Shuna and Shion's musical duet/duel, which in manga format, you just have to take the characters' word for it that it's good.

Like, it's still fun in a "wholesome peace-loving world that sometimes has to stomp down some bad guys" way, but it also just doesn't feel like it's *going* anywhere anymore. Sure, there's the fact it's sort of at the equivalent of mid-game in SimCity, on the road to but not quite at Megalopolis stage, but... I guess what it feels like is a diminishing returns on interest, plot-wise. Most of the truly major obstacles have been removed, so it's now just cleaning things up and continuing the day-to-day stuff; nothing seems like it's on the horizon except civic progress.

That's fantastic in the real world. In fiction, it's... less exciting. It's one thing if it's like Restaurant to Another World, where "fantasy characters come eat at a literal otherworldly restaurant" is the norm. When major wars become a plot point, getting to a stage of complete peace is... boring. (And yet I'm stubbornly persisting with the middling Tanya the Evil just to see if it ever gets there! Figures.)

Four stars because it's a fun story, even if it's more fun animated. Absolutely not a good starting point for the series, though, especially since so much of this feels like the "reward" for certain characters' accomplishments, without newcomers having seen any of the accomplishments.

*Since I barely get to the "full-price" bookstore since... everything's full-price, so given that I'm currently reading for quantity a little more than quality, for "donate my discards to free libraries" reasons, I try to prioritise getting cheap/free books over any new series I follow. It's also, if I'm being honest, a series I'm not exactly excited about anymore, since it's sort of another "manga version of crossword puzzles": fun in the moment, but nothing TRULY memorable. Which makes my goal to "Review literally every book I've ever read (within reason)" annoying, since I've already donated and don't plan to re-buy most of this series, and I almost never find manga donations in little libraries unless I put them there.

Chapter 110: The Greatness of Food - this was a comedic chapter with lots of fun. One thing with Tensura that makes me enjoy it so much is the slice of life scenes so this always does it for me. 5/5

Chapter 111: The Founders Festival - who would've thought they'd incorporate a music scene? Can't wait to watch that animated 5/5

Chapter 112: A Problem Arises - not much to this chapter tbh, I feel like the problem is minor so they'll have no difficulty sorting it out. 3/5

Chapter 113: The fighting tournament - good fight scenes and seeing how much stronger Geld has gotten that he can fight an ex-Demon lord?!? So crazy and I love that for him. 4/5

Looks like only up to chapter 120 has been published in a book so I won't be able to complete reviews soon for a while :(

another great installment!

As a reader of the web novel and light novel series, I am greatly enjoying the manga! The art is good and the story is well paced! I love that even in the action panels you can clearly tell what’s going on without a magnifying glass and days of thesis levels of concentration, observation and research like some manga I’ve read. If you’ve read any of the source material for this or you enjoy fantasy isekai stories with OP characters and political intrigue you should give this series a try. It is also quite funny. Bottom line: I loved it!

Really cool stuff and I love these are very calm and relaxing chapters as we learn more about the festival and see Rimiru and the rest just chilling. Even the tournament is a very chill type of fight and I like it when manga have these types of arcs where their is no big threat, no huge drama just the characters having fun. Also I laughed at Carrion and Gobta their moments were just so hilarious and the surprise Ranga was also funny especially when we learn why.

Tempest hosts its first multiday Founders Festival.

First, as a warmup, we'll have a grand banquet for the VIPs.
Then we'll show off some of Tempest's musical talent and some scientific achievements.
And on the second day is a tournament where we see the true might of Tempest's finest B-Listers vs. Masayuki the Hero.

For a minute I thought I'd read this one already. But I'd just watched the corresponding anime episode. Both are equally entertaining.
