Imagine if this were inheritable, it technically is REM and 3k MP, but they don't allow inherits of monsters of the same active as a farmable. Also, note that Mejedra, Sandaphlon, and Kaguya Hime for this collab REM, although 3k MP, are also not inheritable, as well as Izanami from the June bride REM.
Suppose you enter a dungeon with Sima Yi which makes a 7x6 board as leader, and almost the same LS as DAthena, and DAthena as a sub. If you inherit CTengu on DAthena, you can switch, and have DAthena as leader, and Sima Yi as a sub, but keep the 7x6 board, which is a huge advantage.
TBH, trading an extra inherit for the extra 12 orbs, or 7x6 board is worth it, just make sure you don't use it again. You can also research, when a certain encounter binds the sub in that slot, and switch back, since DAthena is unbindable.
I think Gungho purposely removed the inheritance of this monster to allow players not to do this.
Plus, he has a super low cooldown of 4 turns, and can be skilled up by regular tengu, which takes 1 minute to clear the descend.
