i love how the first three episodes of soul eater very clearly tell us what the characters are like even in a 24 minute episode limit...soul and maka are very capable as partners, they had 99 kishin souls but the thing that sent them all the way back to square one was overestimating themselves. they thought blair was a witch, they didn't bother checking and just. killed her. sure, she has 9 lives, she's fine, but they not only overestimated their ability to tell she was a witch, but they also jumped right into the fight and kept persuing her without confirming at all if she was a witch all because maka was so determined to make a weapon stronger than her mother had, a weapon stronger than her dad who she hates. and soul is so caught up in the excitement of getting the status of death scythe that he just follows along with it.
the episode show us how well they work together as a pair, maka being quick on her feet and soul coming up with a plan out of nowhere, something not even maka imagined him doing which ultimately helped them sell it in the end, but we also saw their weaknesses.
we get a glimpse into maka's insecurities early on with her truly believing soul was leaving her for blair, equating it to cheating and us getting a montage of spirit cheating on her mother with various women all in front of maka (although he was unaware of that last bit). and although soul had spent the better half of the episode picking at her insecurities in a way that could come across as mean spirited, we see his immediate reponse be "how am i supposed to know? cool men don't cheat on their partners." which makes maka realize he was just setting up blair to fall directly into his trap and get her soul. while maka is usually regarded as the smarter partner, soul shows he is a great asset in a fight, weapon form or not, because he's a quick thinker and can transform from weapon to human fast enough for them to get the drop on blair who has cat like reflexes for...obvious reasons.
in the defense of maka and soul, even lord death and spirit think she's a witch at first, but lord death also stresses to them both that if they fuck this up they have to start all over and they don't even...double check that she's a witch? idk how easy that is in this universe especially given this is before maka can see soul wavelengths (which is probably a huge part of why they just went with whatever intel they had) but i'm sure there has to be some way to tell if it's this huge of a deal to aquire one.
and then we have black star who...immediately shows us he could be a very good assassin if he didn't give himself away every fucking time 😭😭 his ego is his biggest downfall but it's also what gained him his incredibly loyal, kind, forgiving partner tsubaki, who saw him be so bold as to stand on top of the building and ask who would work with someone as loud, obnoxious and brash as him and that's honestly probably the best way he could've went about it. how else would he find somebody willing to put up with all of his flaws if they couldn't even handle him as his regular, outgoing, over the top self?
it's also really interesting how tsubaki and black star go over the assassins' rules of silence, stealth, not being seen, etc. followed by black star immediately throwing that out of the window. and tsubaki chastises him. instead of her being the type of girl who just goes along with whatever black star does, she tells him he doesn't understand assassination at all and complains about how they never collect any souls. black star doesn't take any of her words to heart though and tsubaki doesn't take his actions to heart either.
after this we see lord death even say their issue isnt skill, its purely performance, its how they (black star) don't take the mission seriously and tsubaki accepts blame for both of them instead of just pinning it on him. even if she knows he's the problem, she also sees them as a package deal, a team all the way through and she's okay with this. tsubaki also shows that she fully trusts black star as a partner and thinks he will make her a death scythe, it'll just take a little longer than others.
tsubaki and black star both show a lot of strength in battle, with tsubaki being able to transform into multiple weapon forms, black star being very agile, with the ability to do all sorts of moves that most of the other characters are never seen doing. we can see black star go from a poor excuse for an assassins to an impressive one within seconds to mifune and all it took was him actually wanting to do it. we see he can make himself silent and he can use stealth quite well, making it so mifune doesn't even notice him and tsubaki have switched places for a few minutes and he only notices because tsubaki's breathing is different than black star's. we also get to see that even if his ego is a flaw of his, it's also why he can use his wavelength so well when nobody else in his class really can. he has the confidence in his abilities that most of his other peers do not and that is part of what makes him dangerous when he is actually determined to kill somebody.
and he was determined to kill mifune until he found out that he was just protecting a kid. witch or not, angela was a fucking kid and black star couldn't do it. tsubaki could've. she even tells black star they should take they opportunity that was practically handed to them, with plenty of kishin soul's and angela's right there for the taking and he refuses. despite how they have no souls collected, he still choses to walk away and takes the souls back to lord death in a sack rather than having tsubaki consume them because that isn't a real win to him, he didn't kill those kishins.
and then we get to kid's episode and right off the bat we see this dude is talented and a bit cocky but despite his abilities, his ocd gets in the way of retrieving kishin souls. patty's stance is off, he yells at her about it and she responds apologetically, but clearly isnt upset by him yelling, implying it either happens a lot so she can brush it off or she is truly just that bubbly that it doesn't phase her (probably both). liz, on the other hand, tries to reason with him, telling him now is truly not the time as they're in the middle of pursuing a man and when he keeps lecturing them, she just complains, but let's him do it anyways. it's only when he gets a little too out of hand with it does she put him in his place, punching him and telling him he probably shouldnt be talking about how unsymmetrical her and patty are when he has three stripes on one side of his hair and not the other. he calls himself an abomination and cries. they comfort him despite their (liz's) clear annoyance before.
this shows us that despite them all working well as a team in battle, they get caught up in the actual performance of it all, much like black star and tsubaki do, but for completely different reasons. they're plenty skilled, but instead of ego getting in their way like it does with black star, it's arguing (similar to soul and maka) over what seems like little details to liz and patty, but are all consuming to kid.
we also get a line from liz about how "these little rich kids are always so gullible" which implies her and patty are, at the very least, not well off (though we don't know the extent yet). this is when we learn he is lord death's son and that he doesn't actually need to be doing...any of this. he doesn't need to collect souls, doesn't need to train to be a meister or have weapons or work with his team to make them death scythes for his father, he's doing this out of pure want. lord death says because he had two weapons, he needs to collect double the souls. kid, cocky once again, says he wants to collect all 198 + 2 witch souls at once. he's cocky, but they have the skill to back it up.
and obviously they do, kid's a reaper after all and he specifically picked out patty and liz because he knew of their reputation on the streets (plus the symmetry, but lets stick to skill rn)
but again this isn't what slows them down. they go on a mission and as soon as they get there, kid starts worrying about whether or not a painting he has at home is off center and he cant stop obsessing over this thought until the point where he straight up abandons patty and liz when theyre in a pyramid about to fight mummys.
so instead of seeing kid's strengths, we see liz and patty's. the sisters are great at fighting even when the plan goes to shit, likely due to their time before the DWMA. liz shoots with good aim but switches with patty effortlessly when the mummys get too close, not even having to say anything for patty to know to switch with her. and patty shows that she's definitely less scared than older her sister and works better under pressure, hugging the mummys, giggling at them and sticking liz right in one of the mummy's mouths to blow its (metaphorical) brains out while liz complains about it being gross and creepy.
they collect all the souls alone, without their meister and split them evenly just to respect kid's unsaid wishes.
and then finally kid comes back! he's on his gay little skateboard of course, forgot to mention that earlier but it definitely says something about him that it's his primary mode of transportation and its named beelzebub. he gets back just in time as patty and liz have been captured and since they cant use their weapon forms, kid uses his skateboard to free his partners, but that's about as much as he can do before realizing the pharaoh is perfectly symmetrical and he would rather die than destroy it. like he is literally getting torn to shreds by this fucker but he cant do anything about it.
but then the pharaoh steps out of it's tomb and kid sees how asymmetrical it is and that's also what saves them. it almost gets him killed, it ruins missions regularly, his ocd absolutely disrupts his day to day life, but in this instance it also saves them as he gets so mad about the asymmetry that he blows a fucking HOLE through the back of the pyramid and DESTROYS THE ENTIRE THING by unbalancing it.
so yeah, basically i say all this to say the first three episodes do such a good job of introducing us to the main characters and showing us what their strengths and weaknesses are, even if they're played for laughs like kid's ocd, maka's insecurities or black star's ego.
