Transmigrating Through the Anime Multiverse: Daily Life, but With an Item-Based Playstyle!?

After being hit by a dump truck, Shi Jian obtained a four-dimensional pocket in a new world. Great! I'll become the Doraemon of this world. Let's see who my opponents are: Boros, Ainz Ooal Gown, Shadow, Sukuna... Saitama?

Shi Jian: ???

No matter. Let's see who my teammates are. Kaguya Shinomiya, Chika Fujiwara, Ai Hayasaka, Rikka Takanashi, Nijika, Ryo Yamada, Kita, Bocchi... Wait, why are they all slice-of-life characters?!

Well, to survive, Shi Jian has to use all kinds of gadgets to help all kinds of troubled girls grow.

Step one!

Shi Jian: "Bocchi, this is the [High-EQ Lipstick]. Just put it on, and you'll automatically say exactly what the other person most wants to hear. Your mom will never have to worry about your social anxiety again!"

Hitori Gotoh (puts on the lipstick): "Senpai, I like you. Will you go out with me?"

Shi Jian: "It's a deal!"
