First and foremost, I've always hid my reasons for my decisions. Just like when I had the MC choose the Rikugan, it ended up with the mc had affinity with Abyssal and negative energy. This aligns with my storytelling style.
I must emphasize that my story unfolds at a deliberate and slow pace, adhering to its own rhythm. There are specific reasons why I had the MC summon those characters from Tensura.
It's important to note that I didn't summon the MC for war, as indicated by the title: anime! Creating an anime involves various steps. First, you need animated drawings, which the MC can handle. Then, a TV station or internet connection comes into play. But even before those, there's the need for a manufacturing industry, dealing with electronics, metals, and more. And, preceding all of that, you require a source of energy, like fire and electricity. This is why I had the MC summon Ifrit and Pikachu. You may not be aware, but Veldora is an expert in engineering and manufacturing, while Rimuru's versatility allows them to fit into various roles. It's a process that must be taken step by step.
You might be wondering why there's been no mention of a game or manga since Veldora's summoning. Please recall the day the MC returned to Liyue. It's still 2 or 3 days I believe.
I believe I previously mentioned that there's something unusual about the MC's creations, or perhaps I forgot. Nevertheless, they behave like real entities, leading the MC to seek answers from the foxy lady, as a senior.
