Confused, Zerom came to the observation that everybody knew who was this person is and not only is Zerom baffled but so is the person.
"Who is this?" They both questioned
With them both startled they jumped with worry faces on them and then Maka said
"Oh! I forgot, Crona-Zerom, Zerom-Crona"
That being said the tension started to sizzle down Zerom stuck out his hand greeting Crona with a hello following shortly after. Without hesitation Crona shook his hand in glee and also replied with a joyful hello, Tsubaki explained the whole story of how Zerom came to be here at the academy and how they'd found him. After everything was explained everybody started to head home and Tsubaki hugged Zerom goodbye but Maka and Crona stayed behind.
"Without one shred of clue that he was how could you trust him so much even from the beginning?" Maka said in confusion
Crona turned around and explained
"I could tell with my heart that he could be absolutely trusted and besides anybody who heard that story you would be nuts to not feel any sympathy for him and what he's been through I will never be able to go through ever in my life and I don't think anyone could."
The next day Zerom requested to Death that he would be doing missions with Tsubaki and Death agreed and said that.
"Since you will be with Tsubaki too she will be able to help you calm down in your mode and because there will be three of you that means harder missions."
Zerom was perfectly fine about the request but is more than thrilled than happy since he could be with his best friend. So over the past months Zerom's skill progressed and the bondage between him and Tsubaki grow stronger with every passing mission they go on together and he even managed to gain control of his beast mode thanks to Tsubaki.
They were only a few out brakes with Zerom but only when Tsubaki and Black Star where in trouble and he would handle the kishins and then return back to normal. But the problem that not only Zerom noticed but even Lord Death has been into the consideration that Zerom has defeated a number of kishins but couldn't absorb the kishin eggs because he lacked a weapon. So Zerom looked for a weapon but eventually he got word that there was a weapon called Excalibur that could match anybody's soul wavelength but not personality but even so Zerom went to go check it out for him. Zerom arrives at the opening where Excalibur awaits for his meister to take him out and succeed through adventures.
Zerom meets Excalibur in his casing and had the same old routine just like everybody else but the thing with Zerom that took Excalibur off guard is that Zerom actually sat down and read all of those thousand request but at the end he just closed it and stood up.
"Look I don't mind your requests but what I'm looking for is a partner not a weapon" Zerom explained.
With that being said Excalibur just stood there blankly but then suddenly snapped back to reality and said
"I'll be with thee for 2 weeks to see if you are worth my time or even my rules time."
Zerom happily agrees to Excalibur request and walks away with Excalibur by his side but when they exit Excalibur said to himself if he does pass the test then he'll be even greater than him. After 2 weeks go by of missions and assignments Excalibur realizes that he doesn't fight for revenge or for himself but only for the sake of others and Zerom have proven that to him in many occasions.
"You're ready." Excalibur asked
