The Tenshiumou are basically the reverse of Zanpakutou, something that normally remains in a humanoid form until needed, Im thinking of having them have a trigger statement like "I invoke the Contract" to fully use their abilities. But I was going for a more Sekirei approach where they are bonded as long as the user doesn't betray the Tenshiumou or break their bond, other than that they are bonded till death (so kinda like which ever anime/manga you referenced)
