Send “🐷” for my muse to give yours a piggyback ride.
It is, when you really think about it, possibly one of the most mind bending ideas. Minato has done some strange things, some unbelievable things, in his career and yet he’s fairly sure that no one that wasn’t aware of the entire situation would think that even the Yellow Flash of Konoha would be carrying a bijuu on his back.
But even tailed beasts can exhaust themselves and Isobu gave more than his all in getting everyone out of the jutsu trap that had laid, dormant and forgotten, since before the founding of the Villages, a leftover nightmare that had outlived its purpose and everyone that had thought it needed to be laid in the first place.
Minato would never say it outloud, it’s a culture and structure he doesn’t understand and isn’t knowledgeable enough to judge - but sometimes he thinks the tails on the beasts don’t determine who is stronger, but rather the heart inside them.
He can carry this bijuu as far as he needs to for that kind of heart.
He’s just glad Isobu can take human form.
