Max was honestly scared as all hell he knew that he wasn't in this things level of power and the worst part is that he has no ability to use against this knight he honestly he was gonna die here.
Lost knight: you boy your spiritual energy is drained to the point that you can bearly amplify your body to its peak I would have right you off as a weakling bit I can sense some strong with in your soul.
Max: what the hell are you talking about?
Lost knight: you don't know? You're spiritual energy drained so much to the point that you are running on fumes and your body it'd in shape but your vitality is low...ah I get it you had a moment in your life that drained your spiritual energy and vitality and it seems you did it to yourself.
Max: what the hell are you a God damn analyst I don't have an ability I never had never will.
Lost knight: you are wrong you do have one and I'm going to force you to show it to me
The lost knight in blinding speeds got behind max and punched him in the face sending him flying crash in to a wall and the impact made max cough up blood he knew that his body can't handle damage like Sonia but he decided not to just lay down and die he got up and took a stance.
Lost knight: I will make suffer if you don't show me that power.
The knight blitzed towards max again but he was prepared this time the knight swung his sword and max dodged it and countered with a single impact to the face the knight stumbled back but he started to laugh confusing and scaring max.
Lost knight: the single impact lost soul talk about how powerful this technique is but you out of all the single impacts I took while fighting exorcists your is the weakest one.
Max was in shock was this thing right did he did something back when he didn't have amnesia was his current really this weak.
The knight saw this and decided to add insult to injury he charged black spiritual energy but unlike Max's this one was stronger then his the knight went from the left this time max who was in a mental crisis didn't have time to process the attack he was hit by a single impact and this time he was launched with more force and he was both puked out his lunch and blood and on of his arms was in injured this the first time max went through this kind of pain and he was just being thrown like a ragdoll max used his less injured arm and grabbed the necklace mona game him and put spiritual energy in it and his body was healing but due to the severe injuries I didn't heal him completely it just healed him enough that his injured arm could move with minor pains. But thank to the impact of the wall Max is having a major headache he saw flashes of people he never met but he somehow recognized them than he saw black wisps that's all he saw the next moment and he felt like was familiar with these black wisps he reached out and he felt exhilarated as if something was being released
Outside the knight saw how the boy was healing himself with an object he didn't bother to stop him because he wants to kill this boy at his full power but then.
A massive amount of black spiritual energy came off from max and max felt like something from inside his saw was being released and this power he used it before and his spiritual energy skyrocketed along with his body vitality he was too entranced by his own power that he didn't about the memories all he wanted now was to release this power.
Black matter gathered around his arms and he made made makeshift finger claws this caught the knight of guard but if he had a mouth he would be smiling like a psychopath.
Lost knight: show me what you got kid!!
Max and the knight rushed at each other and the clashed the knight was well versed in experienced but max had more on his sleeves he made swords javelins and mantis claws to throw him off by Max's black shape shifting ability and the black knight decided to finish this with a single impact and max responded with his own the two impacts clashed and shockwaves spread out the cave the knight decided to throw max of by stabbing him in the leg but this just made max compress more energy into his fist the knight got desperate and he stabbed him in the liver but this just made max flare up more of his spiritual energy and he unintentionally imbued his fist with the black wisps and the knight's energy was absorbed completely allowing max to pierce his first in the knight's chest killing him
and when max got his fist out his arm was broken again and he decided sense he killed the knight he was gonna be fine so he collapsed due to the pain in his body before he passed out he looked at the left over wisps of black matter in his hand and he was happy that at least this ability what ever it is saved his life and he family passed out but the wisps were drained energy from mona's necklace and healed Max's body slowly
