Finding a picture of this man while he was young is a really big pain in the ass, ya know. 

 Anyways, I hope you like it, despite it is short. I just couldn't find almost any information for this guy ;-; 

 -----------

 "Weismann, he is such an idiot!" The young general cursed, crashing his fist against the table. 

 You sighed, bringing a cup of tea, placing it right in front of him. 

 "I know it is hard for you. First his sister died, and then he decided to run away..." You mumbled, sitting right next to him. 

 "Why are you always so caring?" He suddenly blurted out. 

 "Eh? Um... Well... I just... You know... I care for the people I love." You smiled innocently. 

 He smirked, kissing you rather roughly on the lips, making you chuckle. 

 He will never change. 

 You both deepened the kiss, tongues fighting for dominance. 

 Of course you lost though, which was a pleasant victory for Kokujōji. 

 After you both parted away, the need of oxygen crashing insidey your lungs, you chuckled. 

 "I see that someone is happy now." 

 "At least when I am with you, I am truly happy, (Y/N)." He smiled warmly, pulling you closer to himself, in a warm, tight hug. 

 "What are you going to do with Weismann's research?" You suddenly asked. 

 Kokujōji looked at you, then at the window of the room. 

 "I do not wish for it to fall in the wrong hands, so I will be the one who will keep it safe. I will be it's guardian." He said. 

 This man...

 He was so strange sometimes. But right now you could see it in his eyes... 

 He was dead serious.

 You knew what he felt right now. He lost two of his friends. The friends he loved as a family. 

 "You should take a rest. You need it." You mumbled, snuggling closer to him. He chuckled, his finger making you look at him. 

 "Come with me. I think you too need to rest. It has been a long day after all." He whispered, picking you up bridal style. 

 There was no word such as 'no' in his dictionary. He was a really stubborn man and that can't be changed.  

 "Kokujōji, can I oppose to that?"

 "Nope."

 "But..." 

 "No buts."

 "But I am not..." 

 "Yes you are. Shhh."

  You hadn't noticed when he had carried you to the bedroom, placing you on top of the comfortable blankets. 

  "You are such a man." You whined, rolling around likea 5 years old. 

 "And yet you chose me from all men there were." He said in rather amuzed tone. 

 "Are you surprised because of that?" 

 "Well, sort of... Yes..." He mumbled, crashing his face with the pillow. 

 "Kid." 

 "And look who decided to tell it!" He laughed. 

 "Well, me of course." You stuck your tongue at him. 

 Yes, he may feel bad inside from what happened. But you knew something. This man was worth everything. He was your life. And you were going to protect him, stay by his side, no matter what or who. You just knew...

 You knew that one day... 

 One day... 

 He will be something special. Deep down, inside your heart... you just knew it. 

 'Kokujōji, whatever path you chose, just know... I will be there for you... Always!'
