I am playing this game for a long time. Even it's a idle gacha rpg it's still very f2p friendly then most of games out there. Gacha is also very generous and game progression offers enough resources to level up/ascend characters.I am a f2p player and i have cleared almost 90-95% of the game content and have obtained all characters and ascended(minimum ascension required to unlocking all skills further ascension only increase combat power) 60-75% of characters.

After a year the game has become better, devs added a lot of QoL changes and the game has become less laggy, although this game is originally idle, you can get stuck in it for hours, for example, passing battlefront or gate stages, improving results in guild raids, arena, etc. Not to mention passing "bond" stories with almost all souls. In my opinion, the world has a rather interesting lore, which opens gradually through the main storyline, Tower of origin or the same bond stories in the style of visual novels

One of the most good Games that i Play out there! I am in Gacha Hell for many years and if we are talking about Gacha games with a very Friendly (F2P peeps is a meh but i dont mind them) and Jiggling mechanics then this is one of the games that can make your day smile. In aspect of Play style,  its very simple and easy to Understand,(Specially if you know how to read) Art style of characters are top tier and the only grind here is less stressfull (items and leveling Mats).
