O . o
Which again sounds like a conscious use of his skill with intent to repair a damaged item, thrue the use of additional materials.
Meaning placing damaged items in his inventory don't automagiclly repair them. Cleaned yes, but not restored without intent and materials.
Which brings up an interesting side question. If he was to pickup a car, would it only clean out the rubbish and dirt from the interior, or would he also have to top up the fuel and motor oil before each use?
He could add fuel/oil to the car because it counts as a container for those items, and it would detail clean it every time. It should clean out impurities in the oil, and fuel, if they exist, and separate them in inventory.
Not that he'd ever take the car, considering how busted Shoko's ability is. Just like how a clothing are individual items, and he stores them whole, they aren't broken down to constituent materials and reassembled on recall. Or if they are, they don't appear so in his inventory.
We know the water containers get separated when sent to inventory, but he also can summon the water in another container later on use.
Some small notes about his ability:
It can keep things in time stasis, but it can also age things. This comes up with making vinegar. He can also make glass later (it isn't just sand, btw), so he can 'smelt' things, but he can't heat up food in inventory. Cooking is not crafting. There is a limit on spawn distance, but it is a pretty decent distance. He can chemically mix things as well, so if he understood the makeup of gasoline and found the base materials, he could synthesize it.
There is some other stuff, like how the mages
do learn new spells overtime, or how repeated uses seem to improve abilities in general. But I expect most of that to be in the next dozen chapters or so.
The manga is currently weekly releases on Wednesday, so it should be in the next 6 months to get to Day 5.
