After 5 minutes they still fight mom with mom hold them on the spot.as long they can't push the swords back they cannot win.as i think this mom give them a hints.

"Shiroyuki chan you should use your katana more don't use the thread to much.it has good offensive ability but it also have a weakness"

"Eh ,What?"

"The thread is flexibleand the attack is hard to predict ,but it lack durability make it your weakness,aren't you already see it by yourself?"

"Sorry."

"If you learn how to use katana ,i think you will be the most dangerious in melee match"

After saying that mom face miyuri.

"Miyuri,you have a good speed even better than forvish without magic but you lack battle experience and only use of normal attack is your weakness.there is many chance to use your secret weapon but you don't notice it.you must learn how to use the secret weapon from your mom."

"How did you know my mom degozaru?"

"Because she is my best friend

when i see you ,i instanly know you are her daughter ,it has been 19 years since my meeting with her."

"to think my mom is an hero degozaru."

"well now you should try your hardest to increase your battle experience first."

"Okay, de gozaru."

Then mom face riese.

"Next is Riese,Riese you have a overhelming mana and your cast speed is not bad.but you concentrations is far behind forvish."

"Because he is not a human."

"I agree with that thought,but you must still continue your chant even thought your enemy attack you.if you only hope for your friends to protect you ,you will be useless.i don't hope you to become lik forvish but try to chant one spell and keep it over time and cast it when it is neccesary and use it to gain time for bigger spell and you must increase your spell control ,okay."

"Okay."

"Well let's continue."

After that they do as mom says.Riese as she defend from mom sword she keep chant her spell.She is preparing for a mutiple spell.while shiroyuki and miyuri push the sword bit by a bit after they given a tips.it is only matter of time before they can attack mom.but mom just smiling see this.Looks like she still can defend from their attack.this battle will over in next big attack.Then riese made her first move.

Taken from Royal Road, this narrative should be reported if found on Amazon.

"Eat this 10 Fire bullet."

She cast the spell while dodging .she is pretty good.

"You think that can break my shield?"

As mom saying that she use her 3 swords and it create barrier again.the barrier is really sturdy so it useless to hit it.but riese just smiled and she cast another spell. And instanly each fire bullet spread in two directions before

"10 Fire edge."

10 fire edge appear from both of left and right of mom. can only defend one side so it is a good idea.

"Ara ara,nice idea you lay 2 magic at the same spell and fire it in order so my barrier cannot block it,but still you are to naive. "

As mom say that instanly the 3 sword move back and with 2 sword make a giant pentagon shield instanly the spell vanish when it hits the shield.just how many functions that sword have .

"Haaa i give up use small spell to defeat you.you have a nice shield but can you protect yourself with the shield from both of them?."

"Ah, i forget "

"Instanly they appear just 2 meter from mom.looks like to use the shield before mom control.over 2 swords is not good as before. This is over there is now way mom can dodge both of them at the same time without moving.but this thought is blowed by my mom by he next move.

"Ara ,then how about this."

In an instant another 10 sword come from sky. In reflect i see above oh my god.There is hundred of that kind of sword in air ,she hide all of that in the air.so .all the time mom is just playing around.while thinking that the sword go to them.Before they can arrive 10 sword attack them no more like 12 sword 2 sword from behind them have been recovered.oh my god just how strong my mom to be.in an instant both of them is slash and their mana body is destroyed.riese seeing this try to cast her spell. But before she chant the sword from before stab her chest and her mana body is destroyed.

20 swords and they already lost .oh god how strong my mom is.
