Are they in like, an open arena? Or are they sort of just turned loose in a city or something, so stealth is an option?

Given that Takao/Third is at least a successful serial killer for a while now, you'd think in a stiuation where stealth is an option, he'd definitely get pretty far. .... But because Esuno loves the gag of having him always die fast from ineptitude, that seeming skill probably won't mean anything. :P

Let's be real, though: If it's not Takao going down first just for the lulz, it's Tsubaki/Sixth and/or Yomotsu/Twelfth. People who are effectively blind don't have a great chance in this kind of thing without the diaries on their side. Yomotsu is at least a little capable if we go by him somehow capturing Takao in the Third World; whereas Tsubaki gets a huge boost from her cult of followers, but if they aren't a consideration... she's utterly screwed.

I feel like Karyuudo/Tenth and Kamado/Eighth and Reisuke/Fifth are also all in REAL big trouble in any such scenario. And frankly... if Yuki is on his own in this without Yuno getting his back... he's probably just as screwed. :(

Balks/Bacchus/Eleventh is probably just going to try to hole up in his vault and outlast everyone. But this is not a viable permanent solution, as we well know.

Kurusu/Fourth will probably be around the middle of the pack. Lasts a while but doesn't get to the top levels.

Ai and Marco/Seventh are gonna go far. Easily among the top three finalists of diary holders. But my other two top placers aaarreee...

I've made future diary!!!!

Here's a full line up

Wait, what additional ability did Yomotsu gain from his diary? Beyond just knowing future shit that will go down and using that to his personal advantage, I guess he does prove to have the ability to powerfully hypnotize people. But I always believed that to be something he knew/learned on his own, totally separate from his diary powers. .... I guess the source of that skill is never clearly given to us, though, is it?

This is pretty tough for me to imagine for many of our characters, but here are a few ideas.

First - What Yuki really needs is to know what someone is thinking at a glance. Maybe he can do that once a day to one person? That'd really fuck with all the people who're misleading him or trying to entrap him.

Second - My first instinct is to give Yuno the ability to sporadically remember some of what she and Murmur blocked from her mind when she replaced 2nd Yuno, but... that would require Deus and/or Eleventh knowing that she's not this world's Yuno in the first place, so that's not gonna work. Maybe she should just be guaranteed full lucidity for like, one hour a day. :P lol

Third - Perhaps he gets a little forcefield/shield that lets him take one lethal hit without dying. Since he dies so easily anyway, he might need the help. :P

Fourth - Maybe he should be allowed to see whatever his direct reports/underlings see for a short time. Like, temporary sight-jacking.

Fifth - He kinda got screwed with his diary to begin with, eh? His desire to be able to be "independent" might be something we can work with. Maybe he can sustain himself without food and/or water... or oxygen. He might not even need his gas mask anymore if that were the case. He could just hold his breath.

Sixth - If we're gonna be giving everyone "future sight," can't we at least give Tsubaki "SIGHT"? Yomotsu seems pretty damn well acclimated to being blind; he can manuever extremely well. But Tsubaki's combination of youth + isolation + near-blindness has left her without any such tools or training. Just let the diary serve as her glasses to clear up her vision, ffs.

Seventh - It'd be logical for Marco and AI to be able to locate one another via their diaries. Not just via whatever descriptions appear, but like... actually giving them GPS mapping of where the partner phone is.

Eighth - Her protective instincts towards her children should probably give her some ability to shield a select number of bloggers on her server from attack. Maybe just one attack each, like what I did with Third.

Ninth - Tough one. Given the fact that she often works with explosives that could prove hazardous to her own health — and in light of the maimings she undergoes in the story — maybe she should get some kind of regenerative ability. A slow Wolverine-esque healing factor that lets her regrow lost body parts or something... ?

Tenth - God, we know SO LITTLE about this dude. Maybe he can just like, make copies of his dogs automatically without having to literally breed and raise new pups... ? But of course he could only do it from his own personal location, so that only helps in a conflict if he actually puts himself into the action.
