His quirky sense of humour stems from the hidden quest "Absentee Father" in Trails of Cold Steel II, where he had Class VII desperately pursue him in their Courageous. Unbeknown to them, he was using the Merkabah.

Part of Barkhorn's duties consist of weekly visits to the Nord Highlands and holding a Sunday School for the children of the Nomadic Settlement. In Trails of Cold Steel, Gaius Worzel remembers how Barkhorn's teachings learnt him about Zemurian history, warfare and the Orbal Revolution.
However, each time they come close to finding him, they find that he has left each church before the party is able to arrive. Ultimately, the party is handed a letter that makes Gaius realise that the priest was his former mentor from the Septian Church, Barkhorn whom Sara Valestein recognises by his alias. Here is an excerpt of the letter:
Greetings, students of Class VII.If Gaius is active in the party, the following is added:
You have my apologies for not taking the time to speak to you after you've come all this way in pursuit of me. I did very much enjoy our little game, however.
While it may not have been able to catch up in the end, that Courageous of yours is quite an impressive ship. I hope you'll make good use of it in the future.
I also hear that you are working to improve the lives of this country's people and better the current situation. An honorable goal, if I may say so.
This is an old nation, but change is always possible. With youngsters like all of you striving to improve it, it may have a bright future indeed.
Regardless, I will now be departing for western Erebonia. These are dangerous times, and I have duties as a clergyman to fulfill--and fulfill them I shall.
Good luck to all of you in the future, wherever your travels may lead you.
- Barkhorn, the traveling priest
P.S. I was pleased to hear that you're still well, Gaius. Say we meet again one day under the beautiful skies of Nord.The following P.S. is added to all party formations:
While it was not my intention, I seem to have caused a lot of concern to poor Father Paulo. Please do pass on to him that I'm alive and well.
I also seem to have wasted quite a lot of your time by making you pursue me from place to place. It's not much, but please accept the attached as an apology.
During the Erebonian Civil War, Barkhorn was operational in the western half of Erebonia. After the civil war concluded, he noticed that Gaius was worried about the war situation between Erebonia and Calvard and decided to visit him in Nord Highlands. Gaius explained to him he had a bad feeling based on the destructive wind blowing across the highlands.
Immediately thereafter, a Republic aircraft broke through the 7th Armored Divison's line of defense and attacked the nomadic settlement, Gaius' home. Barkhorn suffered a mortal wound as he protected his pupil. With his dying breath, he bestowed his stigma upon Gaius, passing down the position of Dominion No. 8 to his faithful pupil.
- To honour his teacher, Gaius adopted Barkhorn's red ribbon bound ponytail.
