>>78109989like you said, speedrunning the fastest suspension in hololive production history was already a huge red flag
coming back completely unapologetic and just saying "lol i lost my temper lol", another huge red flag
The big thing though was the "menhera arc" where he started ghosting the rest of tempus for months and months, flaking on several collabs that he was even outright planned for and leaving the others to deal with the "vesper doko" spam. Again never apologized. For added context, the tempus fanbase was really huge on "unity" so this sudden break of group cohesion really ruined the atmosphere for many sisters.
Now his excuse at the time was that he went to japan, didn't take his anxiety meds with him, then went "OH NYO I DON'T HAVE MY ANXIETY MEDS HOW COULD THIS HAVE HAPPENED I'M GOING SCHIZO" and basically locked himself up in his room.
Now, the thing is not only did this not excuse his ghosting, he could have just said something from the start; it also eventually became very doubtful how much of that excuse was even true. Because while he supposedly was crippled with anxiety and "unable to collab", he still collabed with girls. And even after returning home he still claimed he couldn't collab, yet AGAIN colllabed with girls anyway. So many people called bullshit.
Lastly his nature as a shit-stirrer eventually became too obvious. He was always egging on the antis, or for example, raided Kiara and outright said "if anyone gets pissed off about it they can bite my ass" or something along those lines.
