i find the idea of throwing chika interesting, but from another point, they said the amount of time it gets for you to get back is equal to your trion recharge levels, so they'd be actually losing chika for a fair amount of time, if not for days (i can't remember of they had given a specific time for our main characters), before she could come back to aid them. if they did end powering through some of them, then that's good, but i wouldn't consider it as good if they somehow could protect against her shots or, worse, if she actually caugh some teammates in the fire.
Oh! I thought it was a fixed time for everyone like 7h or whatnot. So yeah, you are right, losing Chika would hurt the B team in terms of trion.
About protection against her shots, before anyone from A team got there, Chika should have dealt with at least 1 of their terminals. I think it was said it would take 3 shots from Chika hound. I don't really have timings, however creating a hound would be seconds and Chika doesn't have to take off her bagworm.
My idea would be to throw her to the farthest terminal possible, destroy it in way less than a minute, summon a mount (dog or steed) and quickly go to another terminal to quickly destroy it. If she destroys 2 terminals, it would be 1000 points. She, herself "is only worth" 66 points. Points related, it would be a great investment with huge return.
I know of they did this, it would most likely not be Chika, but someone that can take care of themselves and knows the A rank better, but I think she would have the job done.
Though I think Yoko is a very good candidate for this, if she has kogetsu or hound in her trigger roaster. It has been said multiple times that she is like a solo player in a team, though her friend and operator helps her a lot in rank wars.
Actually, just checked and it takes Chika 8 ibis shots. And her ibis has more destructive power that meteora (yup, I was yapping about hound, but I meant meteora . Sorry for the misunderstanding), right?
This means that she can actually snipe the near terminals from her side with consecutive shooting. Her location would be discovered, but she could use a mount to run away and some other trion soldiers to earn some time.
Actually, with the destruction and he'll ibis would bring, they could also shoot some people to the other side to deal with other terminal. If Arashiyama wants hell, Chika can help with that

Am I the only one thinking that, if team B rank also have a rabbit, they should throw Chika and Yoko to the farthest A point for them to start hell?
Like, they both (should) have bagworms and have low points from the first round. Chika has a fixed shield that protects her from even her own mega hound. Yoko is capable of serving through her skills, specially if almost all A ranks are on B team map side.
Also, although this should be a "suicidal" mission, they can take another rabbit egg/token with them to throw them back (again, Chika would be secure from sniping with her fixed shield). And I don't think A team would expect Chika to be the suicidal one, as through the battle competition, Usamo made a point of always protecting her, for Chika to start prioritizing her safety. Tamakoma-1 will definitely not expect this, since Jin can't tell anyone what he sees from his side-effect.
They could even throw some trash first for A team to not suspect too quickly, like some building parts and what not. In one of the throws, there goes Chika and Yoko as well.
... Well, I'm just rambling, but I do think this would be a good strategy, as they would be able to come back even if they die since this is early on the game.
Also, props to Kodera, since he knows he is being read and asked the opinion of the captain everyone of team A has less experience with (excluding Tamakoma-1)
