It's my personal hc that if the flags would have been alive tachihara and albatross would have been BESTIES (like it's already cannon that tachi likes chuuya's bike and he already acts somewhat like albatross so I think they'd get along) ——— Ooh I like that! Tachihara is definitely somewhat similar in terms of personality and Cmon, he HAS hella biker vibes. If Tachihara had joined the PM before SB I'm sure he could've been part of the Young Bloods, and hang out with them :D
