In addition to action, adventure, and danger, there’s also quite a bit of plain old life aboard the Astra, and whenever the crew is not working against the clock to save their skins, there are little quiet moments of that life: Zack accidentally walking in on a naked Quitterie (and even worse for her, not blushing about it); Funi coming up with a new way to address Kanata (“Aye, yeah!”); or Kanata basically telling the traitor, whoever they are, to “do their worst.”
In the meantime, the crew is going to focus on food and water, not investigations that will waste time and sink morale. While I’m sure the mystery traitor will cause more problems down the road, I’m glad it’s not totally dominating the narrative or the headspace of the crew members. Instead, the crew splits up to find food on the planet Shummoor, a name that sounds kind of like “mushroom,” and thus a hint about who or rather what is the true king of the planet.
Thanks to some friendly Gruppies, one team makes it back to the ship with giant cacti full of water, while the other team has a pretty big haul of delicious fruits. Unfortunately, those fruits spoil almost immediately after being picked, making them unsuitable for storage. This presents a serious problem: their first day’s haul of food will only be good for five days at most; not nearly enough to reach the next planet.
After Ulgar earlier called the towering Yunhua a “big girl” and “useless”, Luca’s thoughtless joking words about being worried Yunhua inadvertently eating all of what little food they have are the last straw. Aries and Kanata find Yunhua’s glasses and a note saying she’s left the ship and will stay behind for the benefit of everyone else.
Naturally, Captain Hoshijima is not going to remotely accept that; each crew member is precious, regardless of their talents or other perceived value. Thankfully both Luca and Ulgar show at least a measure of remorse for their ugly words.
As to Yunhua’s crushing lack of self-esteem, it’s chalked up to Yunhua’s dream to sing like her mother (a famous professional singer) and that selfish mother’s commitment to making sure Yunhua not only never sings to anyone, but remains as invisible as possible.
Even though Kanata has skills for which he’s been praised (and indeed qualities that made him the consensus captain), he can still empathize with Yunhua, for the trauma in his past stems from an inability to do anything to save his sensei. He knows what it’s like to feel useless, but what’s even more useless is to keep feeling that way.
But Yunhua leaving the ship isn’t the crisis of the week, it’s the mushrooms, specifically, when the Pole Tree releases poisonous spores that knock out Aries, Zack, Luca, Ulgar, Funi, and Charce, who at leasts manages to send an SOS to Kanata warning him not to take his helmet off.
Every planet is going to have a bit of an edge of danger to it—it’s built into human nature to fear the unknown—but I like how Astra smartly builds up its threats with clues, while also presenting possible solutions that, while not impossible, still require the crew to work together—or for individual members to do what is necessary when it’s their turn.
Dr. Quitterie is stumped; the medical supplies on the ship can only make the six patients a little more comfortable, but aren’t sufficient to cure them. As Kanata did with the traitor mystery, Quitterie drops her beef with Yunhua running away (and risking everyone else’s life to look for her) and asks her to help out with the patients.
Charce, still barely conscious, figures out the process of the predatory Pole Trees that rule Shummoor, and their symbiotic relationship to the moss and other plants. When Kanata asks if the ecosystem has some kind of limiter on the predation of animals, Charce says there could be an antidote out there: a medicinal mushroom. Sure enough, Yunhua used that very mushroom earlier to cure an ill gruppie. Kanata runs back out there to find some.
He has no luck, and worse, Quitterie succumbs to the spores, having been around the infected so much. That means the only non-bedridden crew member on the ship is Yunhua. Remembering her chat with Kanata about her dream to sing but reluctance to defy her mom, Yunhua steps up and finally does what only she can do: sing to her ill crewmates, sing with all her might, and by doing so create a soothing atmosphere suitable for healing.
As she envisions herself on the stage, in a glittering purple gown, with her bangs out of her face, belting out a reassuring song, Kanata realizes that the Pole Tree won’t allow access to the antidote fruits unless he’s suffering the symptoms of the poisonous spores. So, in true Classic Sci-Fi Captain-y fashion, he takes a huge gamble, removes his helmet, and lets himself be poisoned.
Sure enough, the medicinal mushrooms reveal themselves before him, he eats enough to get back on his feet, and the very gruppie he and Yunhua saved gives him a ride back to the Astra. The other ill crew members eat the mushrooms and recover.
The captain put his crew before himself and they are grateful for it. But Yunhua is even more grateful for Kanata helping her break her chains of self-loathing, leading to her playing a vital role in the crew’s recovery.
As for the crew, they’ve likely learned some vital lessons for future planetary excursions: just because a plant or a mushroom doesn’t have teeth or a roar doesn’t mean they’re not dangerous or deadly. Anything in this vast universe is capable of ruling a kingdom, and mere humans interlope at their own risk.
