A super weak high level player. Is she even high level? I thought she should have been, being Dunbalf's old acquaintance. But this makes her look like a fledgling player.
She is someone whose skills are related to items I believe. Which she sold/used up after doing a bunch of grinding and didn't restock, before suddenly being isekaied. Even the most op archer of all time is limited in what they can do if they are missing their arrows.
Furthermore she is lost in the middle of nowhere and still subject to the same biological needs as everyone else(hunger, etc). Strength has nothing to do with it. She didn't encounter any monsters or anything noteworthy.
This is kinda like looking at a tank and being surprised they don't deal high damage, thus viewing them as super weak. Or viewing a super high dps glass cannon as super weak because they can't tank.
Kagura is missing her main equipment, and is in a situation where her skillset isn't innately suited to handle. Furthermore she no longer has major tools she relied on like the game map, to rely on for navigation
And as a person she is no different from the majority of first world society, who has minimal to zero real survival/navigation abilities outside of what Google can tell them. Certainly not the skills to determine what is or isn't edible in an alien world.
Let alone try something like navigating using the sky to orient oneself and maintain a direction(something that is nearly impossible in a dense forest anyways).
She already did better than most I would wager, by being cautious of the fruit she did find, despite her hunger. Most would've eaten it on sight and probably died.
At the very least wait until she actually fights or does something before just calling her super weak.
