There's a Lot Wrong with My Secret Identity

[This is my first story, and I started writing it on a whim, so I haven't thought everything through. Updates may be slow.] Tsukimi Chiaki should have been an utterly ordinary office drone. Then he woke up one day and discovered the world (crossed out) he had changed. A strange System clung to his leg and wailed that it had accidentally turned him into its semi-broken gacha pool. Tsukimi Chiaki: S-semi-broken? System (weeping bitterly): Basically, you're so unstable that you might switch to a different secret identity at any moment. And so... - Family secrets suddenly emerge at the psychological support center. Young Dazai, Dark Era Dazai, Armed Detective Agency Dazai, Mafia Boss Dazai. Young Gojo, high school Gojo, cult leader Gojo, cursed Gojo. - People suddenly transform inside the newly opened clinic. Patient: Where's my beautiful doctor? Mori the Scum (narrowing his eyes): Hmm? The next second, a short-haired beauty with a huge cleaver glances over. “I'm here. Moved?” Patient (trembling): I wouldn't dare move. - The walking Reaper gets an unexpected break from work. Great Detective: Isn't this a case anyone could solve at a glance? Poe: Want to see the novel I've just written? 010:: The culprit dies. You never know what fate awaits the culprit today. Conan: I have it so hard. - One day, after being tormented by every possible theory, Amuro finally worked up the courage to knock on the door next door. Amuro: I have to ask, just how many people live here? Tsukimi Chiaki: ... Can I say there's only one? [Please note] 1. I drew and designed the cover myself (if you think it's ugly, please bear with me qaq). 2. The protagonist never has his secret identities exposed. He'll have several, but not at first. 3. The secret identities involve lots of different series. 4. Lots of original settings and OOC; these are my own take on secret-identity stories. 5. Please be gentle, and be kind to the System. It tried its best. Theme: Always run toward life with passion
