Ioryogi is in love with Kobato??

Ioryogi fell in love with angel who remind Kobato.
The manga's 20th chapter has shown this angel to have Kobato's hair,
clumsiness, and wonderful singing voice, but her face was hidden.
She sitting in a tree and he helped her out when she fell.
In return, she sang for him a song so sweet, he instantly fell in love.
Kobato may be the angel Ioryogi fell in love with or a manifestation
of that angel that Ioryogi has sworn to protect.

i don think so.

In the past, Ioryogi was in love with Kobato before she's die.
