well ladies and gentlemen.
The art is a commission I asked for the artist with a nickname: tabbychan.
Jin kazama  happens to spend time with felicia, and begins to see in her an image of light that he had only seen while still living with his mae jun kazama, Felicia on the other hand, feels very happy for a human to treat her well and make her start to be more sure of what she believes in the relationship between humans and darkstalkers. And with the touch of that relationship is growing a love for each other.
The event there can be seen as a moment within the game namco vs capcom. but it is at the discretion of each one's imagination.

Felicia(darkstalkers) CAPCOM
Jin kazama (tekken) BANDAI NAMCO
