Honesty is the best policy.

You: ''Very well. If you want to know, I'll tell you everything. Tear has been telling me to contract more spirits for years now and I try, but both the spirits powerful enough to consider and I are very selective on who we accept so it hasn't been easy to find candidates. One time when I was visiting the part of the spirit world where mostly Japanese spirits reside I came across a beautiful pale woman wearing a black kimono that radiated coldness and loneliness. At a glance I knew she was a Yuki-onna but Tear told me that one that powerful may just be the original one, the spirit that inspired the folk tales about Yuki-onna. Upon my request Tear enveloped my spirit in fiery essence so I could survive coming close to the snowy spirit. As soon as I came close, she realised that I was a summoner and believed that if I was powerful enough to approach her, I may be able to full-fill her request. In short that request was to kill her. She had been lonely for thousands of years, no human could touch her without dying of cold, most other creatures would either avoid her or succumb to the cold too and mages either didn't want to or couldn't summon her. She knew that summoning techniques exist that destroy the summoned spirit, to imbue it into a piece of equipment for example, and wanted me to do that. I pretended to but instead used a technique that fuses the spirits of the summoned and the summoner into one. Now, Yuki is like a voice in my mind, I can always talk with her, I can borrow her powers and she can use my mana to manifest herself in the physical world. It only costs me mana to summon her not to keep her in this world, all I do is open the gate for her to come. The powers I can borrow from her are immunity to damage from 'cold'- based attacks like ice and snow, the ability to create and shape Ice around me, and a few ice-type magic spells.''

SG: '' That's quite a story, but do you have any other powers you neglected to mention?''

You: ''Well, I don't know if this counts as a power but I told you I can summon items as well as creatures. These items include equipment for me and my summons, I've been taught Judo, Muay Thay and sword fighting so with this equipment I'm not as weak in close quarters as people assume of a summoner. There's also a little power called infusion where I infuse a power that normally isn't their speciality into a summon to give them an edge in combat. I once infused Tear with Yuki's Ice magic to help her fight a fire based enemy, it worked but Tear said that it felt yucky for her to be infused with ice so I'm not doing that again unless I need to. I really can't think of any other sides of my powers at the moment.''

Upon hearing this, Supergirl stands up and whispers something to Wonder Woman. The three women quickly walk out of the room while excitedly whispering to each other. From the few words you catch they seem positive about you.
