Zi-O Trinity instead of II, but yeah. Next form should be final, and for a while now they've gotten in a pattern of selling a new weapon for it. Might come a little later!

That's a cool book. I like that it's another animal-type book, and that it's just bugs in general.

Like, you have a heroic lion, a majestic eagle, a courageous hedgehog, and every bug ever. I love that.

Also, smoke and bug powers makes me think of bombardier beetles, which shoot boiling liquid out of their bodies at things that want to eat them. Because that's just how my thought process works, apparently.

Reika's rider name is clearly a portmanteau of Saber and Bella, hence Sabella. Eneiken most likely translates to Smoky Imperial Sword, and Noroshi like I said before translates to Smoke Signal. Her WRB is Konchuu Daihyakka, which means Insect Encyclopedia. So it's not just one insect, it's the whole kingdom.
As for Elemental Primitive Dragon, it says it is a combo of Elemental Dragon WRB and Primitive Dragon WRB. So I guess this so-called Elemental Dragon will be set where Touma set his Brave Dragon last episode and it will soothe things out for Touma to manage better. Also he will have access to the elemental powers of fire, water, earth, and wind.

Rider forms are confusing.
Build had:
1)Rabbit Tank (ep 1)
2)RT Sparkling (14)
3)Hazard (20)
4)RR/TT (27)
5)Genius (39)
Zi-O had:
1)Zi-O (ep 1)
2)Decade armour (14)
3)Zi-O II (22)
4)Zi-O Trinity (30)
5)Grand Zi-O (39)
Zero-one had:
1)Rising Hopper (ep 1)
2)Shining Hopper (12)
3)Shining Assault Hopper (15)
4)Metalcluster Hopper (22)
5)Zero-Two (40)
All of these previous riders had 5 main forms.
Debut comparison (Build/Zi-O/01):
1)1/1/1
2)14/14/12
3)20/22/15
4)27/30/22
5)39/39/40
For these guys the debuts are mostly the same time with an episode or two difference, the biggest outlier being Zero-one.
Here are Touma's forms:
1)Brave Dragon (ep1)
2)Crimson Dragon (9)
3)Dragonic Knight (13)
4)Primitive Dragon (23)
5)Elemental Dragon (25-28)
Here it is overlayed with the others:
1)1/1/1/1
2)14/14/12/9
3)20/22/15/13
4)27/30/22/23
5)39/39/40/25-28
Saber definitely is powering through quicker than most other riders. After Elemental Dragon we still have one or two more forms for Saber depending on how it goes. The Reiwa riders are definitely going quicker than Heisei.

Definitely betting that the last legendary sword is going to Tassel btw

I could see it. It would be such a missed opportunity if his sword didn't have a tassle.

Huh, you're right. There has been no Final Form Weapon.

Kuuga had the Mighty Anklet. Agito had the Shining Calibur.

Double had the Prism Bicker. OOO had the Medagabryu. Fourze had the Barizun
Sword. Wizard had the Axcalibur. But Gaim-Zero-One haven't.

And even to this point there were still a lot of Riders whose weapons that carried over from the prior upgrade form over to the Final Form.

DJ Gun, Trailer Cannon, Sunglasslasher, Keyslasher, Fullbottle Buster, Saikyo Zikan Girade, Progrise Hopper Blade. etc.

The closest we even have to another weapon that Saber uses that carries over is the Kingexcalibur. Normally by now we have like, a new weapon to go along with our Rider.

Granted given every new Rider post the first three have been swords, those have been filling the weapon slots.

Something funny is that Ghost and Ex-Aid moved their penultimate/final form weapons to the first upgrade and they just kept it forever after that point, but they dropped that when they realised they could just have their cake and eat it too by simply piling on more weapons.

Ohhh! It even got a unique mold. That's a first for a normal WRB, well, besides Saikou's. Cool!
