Ichinose & Ninomiya ♡1x2 Duo♡ _{Their family names contain "ichi" (one) and "ni" (two) respectively}

These two both have a mysterious aura, like fickle cats. Shiki would be interested in Asuka's worldview, and would listen to her stories etc.. They seem quite compatible. Personally, this is a duo I want to see more of.

Gifted & Genius ♡Duo of Brilliance♡

The Cute attribute sure has a lot of brains. Their relationship would be good, as they encourage each other mentally. Shiki would love the robots Akiha makes! Quite cute.
