I think that Kamito next Contract Spirit will be a "basic" armor and rest of the Spirit will be armor upgrades.

Another thing he could do is just swap out swords to fit the enemy. In the early portion of the series it was talking about how Kamito was at a disadvantage against light due to Restia being a darkness spirit. While Claire was at a disadvantage against metal spirits. So he could for example swap out Restia a steel spirit for a water spirit to fight a fire enemy. Although will Est and Restia agree to do that is another issue.

but est & restia are the only spirits that can compete with the elemental lords, it is possible that kamito might be able to use one of the spirits in the burial chamber

Est could, in her prime but I don't think Restia can(at least going by what we have for now)

All this talk about Kamito's next spirit. What about this sealed one that Sorja is trying to release. I mean all indications are it gets released and is likely part of the next big battle. what if Kamito tames it and it joins the team. My guess is Restia was referring to Leviathan when he said her as well.

I think that Leviathan is another of those strategic-class militarized spirit and not the spirit that the Demon King was in contract. It seems that Jio Inzagi is looking that spirit and I think is Lemegeton. Well if is Lemegeton then there is a big chance that will became Kamito third contract spirit.

alrighty. Either way things are about to get fun

But honestly, i doubth kamito will get new spirit :v

Fianna talked about multiple wives and Rubia kissed Kamito. Well, I don't know what to say. Not bad, I suppose. But Rubia's kiss was just a kiss, without blushing.

Fianna is trying to create the harem fleet. Soon this series will also be a true harem.

She said that kings of past had several concubines.
Well, girls are friendly and not fighting over Kamito. And Restia/Est is fine with it.
P.S.In manga and LN, where the word "choose" is used in most cases, the harem will not exist

Clarie say hello.

She still not stop cockblock anythings look like female (girls, sword spirit) get close to Kamito.

^Every harem has one of those. Even in true harems. In the case of true harems, they come around eventually.

I believe that Rubia will correct Claire (and other girls, if needed)

^I hope Kamito find a way to regain Rubia's emotions first.
Yes, i'm not denying that but it's already 16 volume and Claire's cockblock part still the same while other girls, i rarely see them cockblock Kamtio.

if author cool down Clarie's cockblock, high chance it might be harem end.

Harem end will depend on Kamito more than anyone else.

I don't think any of the girls takes Claire's silly jealousy moments seriously.

That's why I hate tsundere type. Always ruin main character's life.

Mirable you say cockblocking as if Kamito is actually making moves on the girls and failing because of Claire's interference, it's not like that at all.

Even without Claire the situation wouldn't be much different y'know, not unless Kamito suddenly became a carnivore.
Exactly, and so far Kamito hasn't shown any indication of wanting a harem.

Your right, at this point none of the girls take Claire's jealously seriously anymore.

This volume has been really good so far. Really interested in how Muir and Lily are going to escape, or maybe not escape and Muir gets a new toy.

This is one of those novels where first girl ending or open-ending can actually sour my personal rating for it. (Like, seriously, from 9/10 to 6/10).

This novel has the perfect basis for true harem ending. All the story needs to do is slightly develop Kamito toward that direction. But unfortunately, Claire has had too many main heroine moments for me to ignore (like drawing Kamito's attention in a specific way compared to the other girls). The girl has changed considerably, yes, but I still can't bring myself like her as much as the other girls. Re-reading the series, I can't help but think the ending will go her way (if not, cop-out/open ending). Mayhaps, he'll move on from Restia to be with his "new beloved" cause plot.

Ugh, why can't Restia be the main heroine?
