These are just the ideas of kids I've come up with so far. This isn't a final decision so information and whether they appear or not can and/or will change.
Virgo Cranel
-Parents: Bell Cranel and Astraea
-Eldest daughter of Bell and Astraea
-Elder twin of her and Libra
-Half-sister to all but Libra
-Demigod
-Female
-13
-5ft 1
-Both have chestnut brown hair and hetero chromatic eyes. Left red and right indigo. Her hair is long and kept straight.
-Hestia and Astraea Familia
-Level 11
-Mage and healer
-She uses the typical mage attire of a staff and robes.
-She can use fire magic as well as arcanum. She can both heal and fire off destructive spells.
-She inherited a strong sense of justice. She is curious about what her justice is because of her mother asking her about it. To this day, she still doesn't know, but understands that supporting the innocent and protecting the weak give her immense satisfaction. She is surprisingly more mature than some of her other siblings that are the same age, but that can fade away if the right buttons are pushed.
Libra Cranel
-Parents: Bell Cranel and Astraea
-Second eldest daughter of Bell and Astraea
-Younger twin of her and Virgo
-Half-sister to all but Virgo
-Demigod
-Female
-13
-5ft 1
-Same appearance as her sister. She braids her hair.
-Hestia and Astraea Familia
-Level 10
-Frontline fighter
-Prefered gear is a shield and sword.
-Fire magic and arcanum
-The less serious twin. She is more relaxed and will find her own way to do the right thing. Though questionable, they usually end well. The things she comes up with usually worry her parents. She is very outgoing and enjoys helping random strangers which adds to her parent's list of worries.
Orion Cranel
-Parents: Bell Cranel and Artemis
-Eldest son of Bell and Artemis
-Demigod
-Male
-14
-5ft 5
-Same hairstyle as Bell, but blue. He has the same red eyes as Bell.
-Hestia and Artemis Familia
-Level 13
-Frontline fighter
-Wields his mother's spear by his father's recommendation
-Has access to fire magic and arcanum being part god.
-Similar to his dad in many ways. He isn't timid as he will not hold his tongue when anyone is being unfairly treated. He gets embarrassed by praise and sometimes will run away like his dad, but will stand his ground when the situation calls for it. He gets teased a lot when girls are around him. Several men in and outside the family predict he will be a lady killer like his dad and brothers.
Nea Cranel
-Parents: Bell Cranel and Hestia
-Eldest daughter of Bell and Hestia
-Demigod
-Female
-10
-4ft
-Long black hair she let's down. Blue eyes. She is like Hestia, but looks even younger.
-Hestia Familia
-Level 4
-She is a very energetic child, but likes to put that to use by helping her mom run her potato snack empire. Much like her other younger siblings, she gets doted on a lot by her moms.
Xena Cranel
-Parents: Bell Cranel and Aisha Belka
-Eldest daughter of Bell and Aisha
-Third eldest child of Bell
-Amazon
-Female
-16
-5ft 7
-Same dark hair as her mother, but red eyes like her father. It isn't as long as her mother's and she ties it in a ponytail
-Hestia and Hermes Familia
-Level 14
-Frontline fighter
-Uses the same weapon as Aisha
-Fire element magic and enchantment spells
-She is similar to Aisha in many ways, although, she is more tame than her. She still finds a way to crack some not so kid friendly jokes in many moments. Like Alise, she enjoys teasing her siblings and cares deeply for them. She holds a great desire for battle, but will throw her sense of manners when people she cares for are in danger. As such, she can and will react violently when her family is threatened.
Lanette Loga
-Parents: Bete Loga and Lena Tally
-Eldest daughter of Bete
-Amazon
-Female
-17
-5ft 11
-Same hair color as her dad and eye color as her mom. She wears what an amazon would wear, but covers more than the average.
-Loki Familia
-Level 9
-Frontline fighter
-Like her father, hand to hand is her forte.
-Thankfully, she isn't an ass like her father used to be. She is a battle junkie, and is quite upbeat about life. After hearing about how her father lived his early life, she vowed to be better than him, much to his pleasure. She enjoys training those weaker than her in her Familia and was the one who trained Albert and the others when they began their careers as Adventurers when Bete wasn't around or too busy.
I'm going to emphasize once more that this is not final. Even when the story starts, I'll update this as more kids appear and the need arises. This is just to include the bios of the new children who didn't appear in the original. I'll throw in some more as I go, but I'll leave the few I have already for you to see. Again, it isn't guaranteed that they will appear or will appear as they are listed. This is only a list of ideas I've finished so far.
