Asanuma and Ken are now standing face to face at a fairly close distance, Ken then pulls his katana slightly from its scabbard, then scratches his left thumb, Ken then closes his katana back into its scabbard. Ken smeared his blood on the scabbard, with a fairly long line pattern

"Here we go Asanuma"

Asanuma replied

"Okay now it's my turn"

Asanuma then took a little blood on the part of his body that was scratched when he collided with Ken's Yokai weapon earlier. Blood appeared to drip on the tip of Asanuma's sharp nails armor, he then handed it to Ken. It appears that Asanuma's blood is also red like blood in general. Ken then takes Asanuma's blood and helps apply it to the scabbard of this katana Yokai weapon, next to Ken's blood. Asanuma said

"Now let's say our contract. When you and I touch the katana, then concentrate on chanting and taking it seriously in your heart and mind, if you want this weapon to be not only a tool but also a part of you. Repeat until something happens. As for myself, I'll keep this in mind if I allow this weapon to be not only a part of me but also a part of you”

Ken's expression turned serious

"Okay, I understand"

They then stood facing each other at close range, Asanuma then touched his claws on Ken’s katana Yokai weapon, and Ken appeared to be holding his katana. Ken concentrated and did what Asanuma instructed, concentrating.

Shortly after, something unusual happened, a sharp wind blew around them and centered on them. Before long, Ken felt a hard thump inside his body, which immediately surprised him

“I, I feel something happen to me, but I can not explain what”

Asanuma replied

“I don't know about it, but possession mark of this weapon for you is already done. For how you feel, that seems to be a sign of success”

Soon Asanuma looked more and more tired, his breath began to short

"Then I'll go first"

It appears that black smoke began to evaporate from all over Asanuma's body. Ken gave a nod

"Yes, thank you Asanuma"

The smoke from Asanuma's body grew denser, covering his entire body, and he disappeared into the smog. The black smoke disappeared, and Asanuma returned to his glove puppet form and lay on the floor. Ken walked over to the glove puppet Asanuma, then picked it up, with an astonished expression on his face.

From behind Ken, Makoto appeared to be walking towards him, then stopped his steps a few meters away from Ken

“Good, you have managed to gain possession of your Yokai weapon with… noise”

Ken turned to face his grandfather, Ken's expression then turned curious

"Yes. I just felt a jolt inside of me, I don't know what"

Makoto replied

“I don't know, I used to feel it when I made possession of my Yokai weapon. from the experience I heard from several people, they also feel it. No one can explain for certain the cause, but they suspect that something inside us is acting on the Yokai weapons we have. Some suspect that the pounding comes from our souls"

Ken looks surprised

"Yes, I think so"

Makoto replied

"Alright, let's continue our training, we'll pull out your soul chain"

Ken looked surprised

"Wait a minute, what does Grandpa mean by "pull out"?"

Makoto's expression turned flat

“Yes, exactly as you heard. Now, you must stab your Yokai weapon in your chest, then pull the soul chain from you"

Ken looked shocked that his eyes widened, he then smiled awkwardly

“Stab me in the chest with this weapon? Grandpa must be joking"

However, Makoto appears to have a serious facial expression. Seeing his grandfather's expression, Ken then said

"Oh no, grandpa is serious..."

Makoto replied

“You better prepare yourself”

Ken's expression turned astonished

"But Grandpa, shouldn't this weapon not be able to injure me?"

Makoto replied

“Don't worry, this is a different process. But yes, this weapon really can't hurt you, so, by having the possession mark, you will be protected from the risk of death, and if this process failed, you could try again. Unlike the case with people who do not have a mark of possession, they must practice a lot of energy distribution first, so as not to fail to do so, because the risk of failure is death. In essence, just by having possession marks, you have significantly speeded up your training process”

Ken looked nervous

“I don't know if I should be happy or not hearing that…”

Makoto smiled

"Besides, you don't want to back off, right?"

Ken's expression turned serious, and he then gave a nod.

Ken and Makoto are now standing facing each other not too far away. They each appear to be carrying their Yokai weapons. Makoto's expression was serious

“I'll explain why possession of a Yokai weapon is related to the withdrawal of your soul chain. Like I said before, a Yokai weapon that has the mark of possession won't be able to injure its master, so you don't have to worry about the greatest risk”

Ken appeared to notice something that bothers him, he then interrupted his grandfather's explanation

“Greatest? Does that mean there are other risks?”

Makoto replied

"I suggest you don't think about it too much, as long as the risk isn't too heavy"

Ken's expression turned doubtful

“I don't feel well…”

Makoto continues his explanation

“Soul chains are mutually tugged with something that has a soul and is used to restrain Yokais that also have a soul, with the power of a seal. It also affects humans and allows their soul chains to be pulled out, like fishing for fish in water. But, this soul chain needs to be very deep within your soul, especially of course, to reach your soul chain. So, I'll wrap my soul chain around your Yokai weapon, then stab it right into your chest. With the entanglement of the soul chain, this stab will be different from a lethal stab, but under normal circumstances without any mark of possession, this stab has the possibility of still being lethal so it is risky”

Hearing this, of course, took Ken by surprise, so he immediately interrupted Makoto's words

“Wait a minute Grandpa, let me clarify it one more time, stab it in my chest?"

Without looking doubtful, Makoto then answered

"Right, exactly as you heard"

Ken now looks nervous

“Wa, wait for a second Grandpa, I mean, wait a minute…”

Seeing Ken, Makoto immediately continues talking

"Let me explain. As I said before, this soul chain has mutually tugged to something that has a soul, and this chain reacts with Yokai weapons that have been marked with ownership or not”

Ken's expression turned astonished

“Are Grandpa mean, this Yokai weapon has a soul?”

Makoto looked doubtful

"Actually, it might not be like that. Yokai weapons are more like something with soul shards, or something that looks like it has a soul. Meaning, what Yokai and Yokai controllers did to the weapon, might affect it so that the soul chain recognized the weapon as having a soul. Thus, when the soul chain was wrapped around the Yokai weapon, this Yokai weapon became something that could penetrate the soul. This should not be done casually, the owner's Yokai weapon can penetrate the owner's soul easier, because they are "of the same type" and recognize each other as one part, something like that. Moreover, Yokai weapons that have the mark of possession, won't hurt the master, you'll be even safer. Using another Yokai weapon that is not yours to do this would be too risky, even if it could”

Ken's expression looked nervous again, he then swallowed hard. Makoto continues talking

“When I stab your Yokai weapon which I have wrapped my soul chain to you, it will safely reach your soul chain. That's when I will pull the chain of your soul out. That's my explanation"

Ken appeared to have a lot of doubts in himself after hearing all this until he was now silent. Makoto appeared to have expected this

"Before we do that, is there something you want to ask?"

Ken looked reluctant

"From what Grandpa explained, if all that is required for safe conduct is met, this seems technically safe. But, is there really no risk?”

Makoto replied

“Yeah, no risk, I guess…”

Makoto rested his chin with his hand, with a doubtful expression. Looking at his grandfather, Ken replied

“Very unconvincing at all! However, considering there are other Yokai controllers, this shouldn't be a problem”

Ken said trying to cheer himself up. Seeing Ken, made Makoto smiled

“I was just joking, hahaha, so you don't get tensed. This technique can be done with zero risk if done right. In other words, if it fails, it's because of human error"

Ken looked tired

"So, it's true that there is a risk..."

Makoto's expression turned serious

“I won't let this fail, you can trust me. If I fail I will kill myself as a reward”

Hearing this, Ken looked surprised, and his doubts lessened.
