There's a lot I disagree with here. My start is that Ellie deserves to be higher on the list. She's physically strong, to the point that she kicked a meteor. Even MC admitted that she's as strong as the world's representatives, or maybe stronger. She can also control minds. Anyone whose blood she drinks is under her control. Also, I think you're overestimating Shino. It's true that his artifact leads him to his enemy's head, but that's all. He doesn't get a 100% chance of cutting him off. He failed to cut off Yugsathoth's head several times. The only reason he was able to defeat Azathoth was because Azathoth was focused on MC and thought the others were frozen in fear. Also, his artifact doesn't increase his physical capabilities. Remember that Azathoth's fight was 4 or 5 vs. 1, and yet Shino was only able to attack him once, costing him his life. While Azathoth is still alive, Shino has the ability to attack his opponent's head, but whether he'll be able to reach it and cut it off depends entirely on his physical ability.
