Tenshukaku a place that resides the raiden shogun she sits upon her throne as her younger son (y/n) sat at her right side. "(Y/n) you have learned from me and your older brother ever since you were born into the family." His mother said. "Yes mother." He said. "But I wish to speak with you within my plane of euthymia." His mother said as the room slowly changed into his mother's plane. He saw his mother Ei meditating across from him. "You wanted to see me mother." He said as she stepped down from her meditative position. "Ever since my defeat from the traveler I had changed my ideals and how one should accomplish eternity." Ei said. "Yes you have and you have told me about the Great War with the seven and the three factions." He said. "Yes I have told you about it and how it went down." Ei said as he nodded. "Yet you have gained two vision at your time in inazuma and looking at it right now you really need to see what is beyond inazuma." Ei said as she got up and the plane slowly shift back into the throne room. "So you are saying." He said. "You will be heading to school in a city called kuoh and attend the school kuoh academy." Ei said. "Kuoh academy." (Y/n) said. "I entrust my most loyal  subordinate in your travels." Mother said. "You mean Sara." (Y/n) said as the doors open revealing Kujou Sara his mother's most loyal subordinate. "Shogun-sama I will make sure (y/n)-sama is safe during his travels." Sara said kneeling before his mother. "Also I've made sure you have a proper house for you and Sara." His mother said. "Your excellency what do you mean." Sara said. "(Y/n) may be skilled but I think it's best he has a bodyguard and knowing you sara you've been his body guard after my defeat." His mother said. "Yes I will protect him with my life your excellency." Sara said. "Good I know you will Sara." His mother said . "Also (y/n) your old brother will also go to the same school with you." Mother said. "Even though he's a harbinger." (Y/n) said as she nodded. "Very well it's best I get ready for this journey to kuoh." (Y/n) said as he bowed to his mother and left to his quarters.

I was in my room packing my things for this journey to kuoh and thinking about how this journey will turn out. 'Being the son of an archon will they sense the traits of my mothers archon power.' I thought to myself as the door slid open revealing yae my mother's friend. "Yae-san." I said looking at her. "I've heard about you going to school." Yae said as I nodded. "Mother said it would be good that I explored beyond inazuma and go to school." I said zipping my bag. "Here (y/n)." Yae said handing me a purple charm. 

"From me and your mother she did put a lot of thought into it." Yae said. "Thank you I will treasure it." I said picking up my bags and putting the charm in my pocket. "Your forgetting something." Yae said as I remembered as I hugged Yae. "Remember the stuff me and your mother taught you." Yae said as I nodded. "Like how you taught me how to put my consciousness into things." I said as she smiled and nodded I'm glad you remember that. "Young master." Sara said coming in. "It's time to embark the ship from inazuma to kuoh is waiting for you." Sara said. "Alright I'll be coming Sarah." I said picking up my bags. "Do you have your weapon with you." Sara said as I summoned my weapon just like how my mother does. "I question why my mother pulls things from her chest especially a sword." I question myself. "That's your mothers ability." Yae said "Sara meant a physically weapon." Yae added. "Hold on." As I ran quickly and grabbed a spear my mother forged for me.
