Hey guys Flipkicks here and today I bring you is a new crossover story called 'A Promise', my 4th attempt on a Bleach X Fairy Tail crossover story. Unlike my 3 stories where Ichigo is in the Fairy Tail world or transported, I'm going to have Erza Scarlet be in the Bleach world and possibly other characters from my stories be part of the story.

There are going to be other elements from some of my stories that I'll be thinking over carefully. I wanna know what elements from my stories such as Ichigo having the Devil Bringer from my 'Reaper of Beacon' and 'Reaper's Magic Games' stories to be part of this story as well.

I do not own neither series

Kurosaki Residence, 7/3/2XXX

At the Kurosaki Residence, the family of 5 were currently relaxing in their home while his younger sister, Yuzu and Karin are still sleeping in their cribs while Isshin Kurosaki was looking at the window.

"Are you waiting for something dad?" The young Ichigo Kurosaki asks his father, who grins at his son's question.

"We're waiting for a friend of mine and she's visiting with her son or daughter perhaps.." Isshin stated to his son, who tilts his head to the side.

"Why's she bringing her family to our clinic?" He questions, "Is she sick or something?" Isshin only laughs from his son's innocents.

"No my boy." He kneels dow to his son's height, "My friend is visiting some of his relatives in Tokyo and she decided to call us ahead that she's coming."

"Is she a nice person?"

"Yes Ichigo, she is nice and I heard she has two kids, 1 older brother and a younger sister. Just like how you're the older brother and you have two little sister."

"Yay!" He cheered as he can finally make some friends for his age. "When will they be here?"

"They'll be here in a couple of minutes. Don't try to be loud for Yuzu and Karin's sake, their still babies after all." Ichigo nods to his father's orders. "Come on, go eat your breakfast, your mother will be upset if you don't eat." And with that Ichigo scurry towards the kitchen, with his mother coming out of the kitchen.

"You have something in plan Isshin dear?" His wife Masaki looks at him confusingly.

"I think it's about time we introduce our son to my friends daughter or son." Masaki scowls at her husband, "Its all in good intentions dear. I think it's time for him to make some new friends." Isshin stated to his wife, sweat dropping a bit in fear of his wife.

"Are you sure that it's all in good intentions Isshin?" Her husbands gulps, "You don't plan on..." She didn't finish her question as the doorbell rings, saving Isshin a few more minutes before facing his wife's wrath.

He quickly rushes at the door and opens the door, "Ah Vanessa, it's good to see you again." He says with a smile on his face.

"Hello Isshin, it's been a long time." She replies and hugs her old friend. "This must be your wife you've told me about." Isshin quickly tries to make sure to keep his composure.

"Yes, this is my lovely wife Masaki." She walks up to her and the two shake hands, "Masaki, this is Vanessa, an old colleague when I was getting my certification." She introduced herself to her best friend's wife.

"Oh this must be the lovely Masaki you've mentioned to me during those lab experiments." She didn't know that this was his wife back then, "So how are you guys?" She asks nicely to married couple.

"We've been good," Isshin replies, "Have a son and now twin daughters." She looks at him surprisingly, "Ichigo!" He calls out to his oldest, who rushes towards his parents side, "Ichigo, this is my friend Vanessa. Vanessa, this is my oldest son, Ichigo." Vanessa said to Ichigo. She is a beautiful young woman with a voluptuous figure around the same age as Masaki with very long scarlet hair and brown eyes. She kneels down to Ichigo's level and smiles, "Nice to meet you Ichigo." She looks back at Isshin, "He reminds me of my daughter. He's 5 right?" Isshin nods to her question, "Erza, can you come here?" She asks her daughter to come by her.

"You have a daughter?" Isshin curiously asks. 'Gee...I didn't think I was right on that one.' He mutters to himself in his head.

"I have 1 daughter Isshin and she's my pride and joy." She corrected the doctor and her daughter shyly hides behind her mother's leg. "There's no reason to be nervous Erza." She assures her daughter, "Isshin, Masaki, this is my daughter Erza. Erza why don't you say hello?"

"...'Lo." Her daughter shyly says.

"There's no reason to by shy Erza." Her mother assures her daughter, "Why don't you try to talk to Ichigo." Her daughter looks up to see a small boy about her height and about the same age and slowly walks up to him.

"Nice to meet you Erza, I'm Ichigo and ichi for first prize and go means for guardian angel, though my dad told me me that my name means "he who protects"." He stated proudly to the girl in front of him. Erza continues on being shy as Ichigo drags her to his room, "Come on! Let's go have fun!" He couldn't wait to have a fun day with someone new while the parents only smile to see him trying to make her smile.

"Is he always like this?" Vanessa asks the two parents.

"Ichigo only made one friend so far and that was during his training sessions in town. The girl he made friends with is Tatsuki Arisawa and she's exactly the same age as both of them." Masaki stated to Isshin's friend.

"I see, I think it's for the best for Ichigo to be her first friend." Vanessa stated to the two parents, "I hope that everything in the future for the two of them aren't separable." The two parents look at Vanessa confusingly.

"Does this have to due with our son?" Masaki asks her, which she shakes her head.

"No but Isshin thought it would be a good time for her to have a best friend she can rely on. As she grows older, my husbands side will want her to follow his footsteps and be something that she isn't destined to be." Vanessa stated to her.

"Is that why you wanted her to be here?" Masaki asks her husband, he nods.

"This is a favor that I owe Vanessa during our time in the old clinic down town." Isshin stated quietly to his wife, "She said some puzzling details when she called me a few nights ago about 'seeing ghosts'. She's Spiritually aware just like Ichigo, Masaki. I'm not sure what I can do but I think it'll help her and make Ichigo a bit sociable to kids his age."

His statement made true when Vanessa called him. She has been 'hearing voices in her head' to seeing things that aren't there so Isshin thought it was probably her but not her daughter since he was probably the one to 'expose' her to his Spiritual Pressure, even though it's been 5 years or so that could had expose Vanessa and possibly Erza when she got pregnant.

Masaki looks at the stairs where Ichigo is trying to break her shyness and smiles, 'Maybe this isn't so bad. I hope to see him break her shyness and the two become a inseparable pair.' Masaki thought as she smiles to see her son making a new friend.

As the adults continue on with their talk; the 2 children, Ichigo and Erza, were in Yuzu and Karin's room, where the two were looking at his sleeping baby sisters.

"They're your sisters?" Erza shyly asks him,who only smiles.

"That's right! The one with black hair is Karin, she's the youngest while Yuzu is the oldest." Erza looks at him confusingly, "My mom says their twins and were couple of minutes apart." Ichigo would go on telling that it maybe a pain that they cry since they are only babies but Ichigo loves them to death, making Erza smile a bit. "I'm going to make sure to protect my sisters from anything as they grow. I'm their big brother and it's my job to protect." He stated proudly to Erza, quietly thought since his sisters are still sleeping.

And that ends the short prologue chapter. The chapter was set years before the bleach-canon and the story will take place either in the Arrancar Invasion, the Fullbring Arc or during the 1,000 year Blood War. There is going to be a romance in the story, which is still going to be develop as the story progresses.

Also I'm a bit curious on what you guys want to see from my previous stories listed in my profile since I'm going to be having some elements from those stories. I added a poll on my page and its a list of possible girls for Ichigo's harem. The story is going to be a mesh of what I previous written and still currently writing.

I hope to hear what you guys think of the short chapter and as always, I'll talk to you all later.
